I put this on my cat to try and de stress her from the other cats coming in our garden making her spray in my house.
I put it on as per instructions with 2 fingers between collar and cats neck.
I found the closure of the collar very tight to close and had to get someone else to do that up for me while I held the cat.
She had only had it on a few days and I noticed she had the collar stuck inside her mouth on her teeth.
Once I managed to catch her she was yowling and drooling and very stressed.
I tried to pull the collar from over her head but too tight, then tried to undo the clip but to tight.
I lost her a couple of times round the house and had to find her as she was hissing and scratching in distress so having difficulty holding her.
Luckily I had a pair of safety scissors in the drawer which my boyfriend managed to cut it off with.
She was very upset and stressed after wards and I cut the other collar off my other cat too.
So the safety feature on this collar is not up to standard. It needs elastic in it like normal collars.
If I was not home or she wasn't an indoor cat things could have been alot worse.
