So my partner recently got me the "Tractive cat mini" device to put on one of my cats. I've been worrying about him more lately since he's getting old (turning 14) and loves to spend a lot of time outside. I recently got the device and my first thought was that it's way too bulky for him, my mother also agreed. Since my partner didn't ask me before buying it I personally don't know much about it and would like to hear from other people with similar cats to mine. For reference my boy weighs around 3-4kg if I had to guess, is pretty lean, has long fur and a shorter neck (that's what I'm most concerned about). Pictures attached for reference, I couldn't find any better angles or poses.
