I third the recommendation to keep your cat inside. Having said that, I think a big problem with the device you're considering is that it's attached to the collar. If your cat loses his/her collar, all you'll find is an empty collar. Seems like microchipping would be the better alternative, but I have no personal experience with that either.
I had a Houdini cat also that was an indoor cat. We never let her out but she escaped on occasion. DEFINITELY do the microchipping. If all else fails and the pound or a vet receives your cat they will know it owner. As far as trackers: I have seen a few available through search engine but they all seem to attach to the collar. This would only work if you have the non-breakaway collar which could be hazardous if your cat is prone to catching himself on it. I guess you could use it with the breakaway collar but if it breaks off, you still won't know where your cat is.
We too have a cat who was quicker than greased lightning at escaping as the door was opened. After he had a nearly fatal outdoor adventure and we found him unable to move his legs at all, we kept him indoors during his long recovery. He's an indoor-only cat now, and enjoys his life indoors. Ideally all cats would have safe outdoor enclosures to enjoy. It's a shame so few of us cat pals have the resources to make such enclosures available.
I put mine on a leash when we are outside. She would rather be free to roam, but she will actually run up to the leash and put her head through the loop, I guess she's rather be out on a leash than inside.
My indoor cat is microchipped, has a breakaway collar with a bell and a tag. She never goes outside (other than the veranda on the second floor), but if for some reason she should be outside, I want the best possible way of finding her.
Getting a microchip costs about $40, takes less than a minute and is virtually painless. It's inserted in the loose skin between the shoulder blades.
Oliver- The only 'tracking devices" that I have run into are rather large, and very expensive. The are normally used on big, expensive hunting hounds and dogs. I do agree with the majority of posters, that if you are not on a big farm- your kitty will be safer and live longer inside... a tracking device will not keep your little one out of the road.
We follow the trail of destruction, inside and out. We have an odd little kitten that we found on our doorstep during a freezing rainstorm that has decided to stay with us. She breaks through the screens in open windows and reeks havoc on the neighborhood then comes back through the same hole or, if closed, will bang on it or the door, until we open it. She will also destroy anything in her path if she determines it to be a nuisance to her. For example, if she wants to lay down where my son is building legos, she will swipe them out of her way and if they are too big to swipe, she will pick them up with her mouth and throw them. She has also done this with a potted plant. So, we follow the trail of destruction. Our other animals, a large cat, great dane, and a st bernard, are tired of her antics so they usually put a stop to her antics right away.
Also- to me a micro chip is necessary... my dogs, cats and horses are ALL microchiped - just in case! (I admit , I did NOT microchip my husband's goat...she is 12 and will NEVER leave...). I did think of microchipping the goat with someone else's information....hmmmm
HibbiddyJibbiddy- OMG- we have your cat's sister! She will periodically attack the horses, they are a little concerned about this, so they will move away from her. And, yes- I stupidly micro chipped HER, so we will never be rid of her,(or the goat...).
I cannot track, no. The chip has no power source, so it relies on someone finding her and bringing her to a vet or shelter or similar. The problem with trackers is that they need a power source. And they are usually pretty heavy.
I think the problem with microchips is that they rely on the cat being found/brought somewhere to scan them. I live in the woods, basically and I'm more concerned with wild animals getting my cats. We also have a problem with people in the neighborhood keeping cats for themselves. Unfortunately, my cats all refuse to wear a collar, the breakaway kind they get off in about 2 seconds and the will somehow work their way out of non-breakaway collars. I recently had one cat go missing and it's hard not knowing if a wild animal got him or someone took him in and doesn't want to turn him back into us. That's why a locator would be nice, but I understand needing a power source makes it difficult.
Patti, Please KEEP the sister. We have tossed around the idea of loaning her and our gaseous great dane to the DOD to end the wars in the Mid-East (we have a very detailed plan w/little to zero casualaties) but we decided that we do not wan our fuzz buckets, however rotten, weaponized.
We are also unsure of the kitten's actual species. My son now has me suspecting she might have been sent from an alien race to subdue us and takeover the Earth. Please be careful of yours in case this is in fact the truth. My son is not to that part in his THE BOYS' BOOK: HOW TO BE THE BEST AT EVERYTHING, but he did teach him self to tie a tie and we are prepared for a zombie apocalypse. I'll let you know how to prepare for the alien invasion as soon as he reaches that part.
I think you seriously need to consider learning about how to train a cat. She's spoiled (or mental) and that is your doing for tolerating it. Cats do very well with time-outs. A cat time should last no more than 1-2 minutes. The other option (if possible) is to time yourself out and ignore her completely for those 2 minutes. Depending on the cat (your sounds like timing her out in a closet or bathroom) one usually works better than the other. Good luck.
I used to time my cat out when she would climb the Christmas tree. As soon as I would open the door, she would run right back to the tree....
I tried a water bottle when she would do things she shouldn't. She would see me with the bottle and hunker down, look right at me, and only move once I squirted her IN THE FACE. Anywhere else, she just stood there, braced for it.
