Seventeen: One day, two wanders

Leo went out for a double wander on the 1st of February – which was a Monday morning – having gone out at seven in the morning and seemingly investigated the graveyard at the bottom of Deep Lane. There is a lot of tree cover there and the data shows a long gap between the graveyard and the rest of his adventure.

That adventure starts at about Eight and sees Leo darting between houses. He does not seem to go into the houses so much as check that the houses – which he has probably marked – were still there. He does not seem to go to the houses in any proper order zig-zagging between outposts.

At Eleven Leo behaves differently.

Rather than charging between outposts Leo goes on a tour starting to the south of the house on Crescent Walk and walking slowly through the gardens towards Bull Grave Woods going deep into the Wood and off tracking for a while before returning to the gardens and a tour and heading home.

Sixteen: Nothing much to see here…

This was a trip Leo took at the end of 2015 on another of those rainy winter days. We notice him wandering through a field staying close to a wall probably for shelter.

Fifteen: A massive sleep

Since we last talked, cat tracker enthusiast, Leo has been to the vets after a swollen saliva gland saw his face puff up. An antibiotic course and a bit of time in the house sorted him out and he rewarded us with 4am cuddles.

Today started misty and overcast in Bradford. Leo started his tracking early at half past seven and untracked some twelve hours later. We last saw him disappearing down the neighbours drive. The data was not brilliant. It has a few jumps in it and ends early but shall we see where he went?

After a wander to the edge of the wood, but not into it, it was all paws to the field for Leo as he charged into the large dew covered grass to explore and hunt. The hunt seems to have ended quickly judging by the amount of zig-zag runs in the same area which tend to denote “mouse play”. Certainly something is being chased around and around.

Leo goes further into Bullgrave Woods but not far and he spends some time around the wood, an hour or so, before heading back to the street and clearly at one point going into the other neighbour’s house (staying briefly, he does not get along with that neighbours cats) and heads into his home where he eats and is away back to the woods.

  1. 07:55 Leo under cover for 38 minutes.

  2. 08:36 Leo under cover for 7 minutes.

  3. 08:46 Leo under cover for 6 minutes.

  4. 09:33 Leo under cover for 14 minutes.

  5. 09:51 Leo under cover for 9 minutes.

  6. 10:23 Leo under cover for 229 minutes.

  7. 02:18 Leo under cover for 22 minutes.

However looking at his Lingers chart we see again that he spends a lot of time under trees and in fields. His 7:27 stop is, I think, hunting and his 9:50 Linger could very well be sleeping under a tree.

The most interesting part of this whole tracking comes at 10:23 when we see that Leo goes under cover a few meters from the house – probably his last track before he goes through the cat flap – and stays undercover for 229 minutes. This is a four hour sleep! We’ve always wondered what Leo’s diary is like for the day but this seems to suggest he gets up, has a small hunt, has a patrol, and after three hours out he comes back for a massive sleep.

Fourteen: Where does Leo linger?

Leo has been poorly. His tummy has been bad and he has been listless and he has not been eating his dinner. I’ve been worried about him and what could be making him poorly and so I thought I might see if this data – which tells us where Leo goes – might also be used to tell us where he stays. If we know where he stays then we might note if he is eating something bad somewhere or he is stopping in unusual places.

And so while I have the Leo movement data today I have also written something to tell me where he stops.

It was a wet day and overcast.

First we start off which what might be bad data – Leo is all the way to the East of the map – but he seems to start running around his own back garden before heading off in a new direction South down Bullgrave Woods and towards St. Anthony’s School (Stay away Leo, I hated it!) where he heads into the large playing field behind the houses at the bottom of Crescent Walk.

He does not go as far up as “Pannies House” – the home of my mate Richard when we were kids – but he is behind that row of houses. He exits pretty quickly and works his way back to the gardens around Crescent Walk. He has an explore of the back gardens going further West than normal too.

He stops at the edge of the houses rather than going to his favourite field and then returns back to run around my garden again.

So far, so Leo, but let us look further.

First Leo went just under 5k. That is just over half his usual distance on full day tracking underlining his being not that well, or at least not himself.

Lingering

I’ve written something to find out where Leo lingers, and were he goes off tracking (into a house, for example, or under tree cover)

Some technical stuff for those interested. Lingering is when Leo’s GPS ticker – which ticks every ten seconds – reports being within the four meters according to the Long/Lat reported. If Leo has twelve ticks all within 4ms he has lingered.

If the tick is outside of four meters there is a tolerance (for bad data) but as soon as a second/third tick is outside then he is no longer considered to be lingering.

Being undercover detects when Leo’s tracker does not report for an extended period of time (around eight minutes) by subtracting the time between ticks. I’m refining the plug in and will stick it on GitHub soon.

  13. 02:41 Leo under cover for 7 minutes.

  14. 03:22 Leo under cover for 179 minutes.

If we long along the maps we see Leo hanging around in a garden, then on a road (daft Leo) and then at the corner house at the bottom of Crescent Walk. These are the locations where Leo has stopped moving long enough that he must have shown an interesting in something. His last Linger is in the bottom of the garden. Remember this is where the linger started. I linger could be being stopped, or just walking slowly or circling a point.

An improvement to the lingering would be to note how long he has lingered in a location.

If we look where he has gone under cover we see the first two are for dense tree cover. The third he seems to go under a roof (perhaps) and the forth may be similar as may the fifth. It seems that tracking drops out at a few points and it might be a good improvement to show where it comes back. I suspect that the under cover shows more the limitations of the tracker than much about the kitten.

Mystery solved

Leo is going into a neighbours house and eating biscuits and meat that has been left down for too long. Hopefully we can get him back on his own diet and he can get back to being himself.

Thirteen: A year of living outside

Monday the 8th of June 2015 was Leo’s first anniversary of his cat flap being installed, and his life of a cat who can come and go as he pleases starting. For one year we have watched him dart out on a morning, stroll back at night and – if we are very good – bound up the garden to see us.

On the first year anniversary Leo was tracked for an all day wander. Shall we see where he went?

Download

Leo was out for seven hours. We found him in his donut on bed when we got home, and in that time he went over 9km. He has a long route today so we will look at his highlights.

Sometime in the morning Leo goes into Bullgrave Woods. He path takes him over the road and down to where Bradford Beck runs through the Wood. Leo spends a good deal of time on the banks of the beck running back and forth. He must be playing at this time, probably at hunt, and he must feel safe. The area itself is a little exposed to other animals and people and Leo would not spend so long in it if he did not feel safe.

Just as he does in the back garden he will be wary if anyone else is present and find cover.

He may have been “playing” with small animals (mice, etc) at this point.

He finishes his game and climbs up the Scholemoor side of Bulgrave Woods but only briefly and never breaking tree cover. He rather quickly comes back and breaks for home where (and this is hard to see above) he goes into the house for a couple of hours and probably goes to sleep.

When he comes out he returns to where his patrol left off which is the edge of Hunters Park Avenue where the Woods reach a field and walks a different route to return to the side of the Beck before returning to the street for a fairly lengthy wander around some houses and probably another sleep.

His last mission of the day takes him to the higher part of the wood near the field where he seems to climb trees. He altitude differs by a lot of meters for him to just be going up and down the banking. It was a hot day and he did not stray into the field or towards the Quarry. Instead he headed back for another sleep.

So a very Leo-like day. A little play, a lot of wandering, and a good few sleeps.

Twelve: Working from home

I was working from home this Wednesday, and Leo was working with me… if my job was hunting and butchering voles that is! Seriously though it is not, my job is web design and Leo’s job today seemed to be sleeping. What did he do between his sleeps?

Download

First thing to note is we have loads of great data from the G-Paws tracker. Second thing to note is that it was a hot day today and Leo spent more time in the house than he did a few months ago. He went 5.6km in just under ten hours which contrasts to the 7km he was doing in five in the winter.

The first thing he does is go to the Quarry and have a proper investigate of what is there. He moved around the edges of the Quarry which I think it is not unused but I’m not sure. Then he comes back using his usual routes.

This tracking looks like Leo walking all the routes he normally does but slower than normal. He has had a proper wander, calm and casual, and seems to have tired himself out judging by how much he slept tonight.

This data though shows the need to come up with a new way of mapping cat tracking data. At the moment I used plug ins designed for showing bike rides. I need something a bit more suited to showing the speed of movement and how it differs.

Eleven: Sunday Spring Morning

Leo in springtime. He is out on a Sunday morning. Shall we see where he went?

Download

The first thing Leo does is wander to his field probably for his morning wee. It was a cold Spring morn and Leo seemed in a bit of a rush. He only went 3km and spend his time doing his patrol near the walls in the field, and then down to his play area in the woods.

Following that he wandered down towards the quarry but doubled back on himself half way there and came back to the streets of Crescent Walk where he played in the back gardens of the houses around the corner before returning home.

As standard and steady morning wander for an excellent kitten.

Ten: Spring time Leo

Leo tracking in Springtime – we suspect – will be different to his Winter walks. He seems to be out most of the day and is normally not back in the house until after Eight or Nine at night. He is out longer for the walks when he goes out. Shall we see where he goes?

What we have now is a kind of super-walk made up of the three tracks his GPS collar gave us.

Download

The first thing we notice is the fullness of the data. We have nine hours of Leo movement which goes over 7,000 meters. It started with him jumping from my arms in the garden and running off through the fence at half past seven. He goes straight to the field and waders under the tree perhaps answering the “where does Leo have a wee?” question. The section of trees he wanders around and under isolate an area of the field away from the cows which could give Leo time and space to explore but he is pretty quickly off into the far field and towards that Quarry.

The Quarry is much further than we thought he would go and he is only explores towards the sides rather than the full area. He wanders along before returning along the walls of the field and finally back to the houses of Crescent Walk. He checks out the collar-losing lands behind 43 and seems to disappear into Steve’s house for a while – hmmm… Steve – but heads off to Bullgrave Woods where he spend a long time running back and forth in a small area.

I fear for the small animal population of that area. I worry that is a mouse meeting Leo.

Stunningly though the splurge of movement in Bullgrave Woods which can be seen towards the middle of the map represents 2km of the 7.3km Leo moves. In the space of about 50m Leo runs 2km. This include a brief run over the beck and probably a lot of climbing up the side of the valley that the beck is formed in before our data gets sketchy and runs out.

So we see that in this first Spring tracking Leo has expanded his adventuring to include the edge of Filler’s Field Quarry and we have discovered where Leo does what he does during the day but what he does is a mystery so far. It is probably play. His routine is to look at territory which is obvious as he walks the edge of it and – having patrolled – he hunts and practices hunting.

Nine: Another Saturday wander

Leo popped his tracker on for a wander on Saturday. It was wet without being rainy and we were about (at one point I washed our cars) and he was around and about the house and garden. He took off his tracker at about two.

Lets see where he goes shall we…

Download

The first thing to note is that Leo spends a lot of time around our house in this. He is out for six hours and early in that time he was hanging around with me as I washed cars. He watched the washing and then scampered away, and then came back. He did this for a couple of hours.

Then he set off for an explore. He took what seems to be his usual route down through the gardens and and into the Woods. We’ve walked his path there. There is mud and probably things to hunt. We lose Leo in the woods but find him again later nearer home.

He explores around the neighbourhood for a while. This time last year Leo was not allowed out and the gardens probably have some new smells and interest for him. He spends about an hour looking around Crescent Walk before heading off away… far away…

To Woodvale Way. This is far for Leo to go. He crosses the stream and climbs the bank at the other side of Bullgrave Woods very quickly and he might even go into someone’s house, or just into the garden, and then he returns equally quickly. Leo does move quickly, we know that, and these long darts are common when he goes to new places. I’m not happy at him going so far, but he is an adventurer.

He returns and does a heavy patrol session. He came into the house for a time and then kept wandering away. He goes up Crescent Walk and onto the back of Hunters Park Avenue (the rise section) again showing his darting behaviour for when he goes further than normal. This contrasts with his final behaviour where he goes slowly towards the far field and we lose him as he runs under trees.

That is a total of 5k running for Leo, and he went up 1k and down 1k. That is a big adventure for a small kitten. It seemed to tire him out as you can see…

Leo, right now

Eight: On a Saturday

Saturday and Leo was tracked all day as he left for his early morning wander.

Download

Once again we pick him up in the field working his way back. He wanders back to the back gardens of Crescent Walk and stays penned in between the roads. I’m very pleased with the idea that Leo avoids crossing roads but the road itself was still icy yesterday – we have out own micro-climate at Crescent Walk – and perhaps he decided that he did not want to cross the road in bad conditions.
