GPS/Radio tracking pet collars

Does anyone have any experience with these??
This is what Neil wants to get me for my BDay for Bakker. I haven't checked out any of the websites yet but there is one that sounds interesting.

I've never heard of them but it sounds interesting! Let me know if you get any info on them!
My Lady was missing for 11 days! (She is now grounded to indoor only!)

There is a "cat traxx" system-$399 for one collar and receiver. Spoke with my SIL and she said it would be worth the cost vs worrying about the cat (bakker).
The dog collars are much cheaper but then again too big!!

WOW!
that would put me at about 1200.00!

Hi

I'm not sure if this will work for cats, but equally, for something this accurate (ie that doesn't just go "your cat is within 400 metres of your house", which you kinda knew anyway), I haven't seen anything smaller.

I have seen this sort of product in a harness that holds the device to a dog's chest. It's about the size of a credit card, but thicker, I think 1.5cm/about half an inch.

Anyway, take a look at this GPS tracking device.

Cheers
