I put a collar on my wayward cat a couple of weeks ago due to his wandering. It's definitely fitted correctly as I had a vet check it, and although he was skittish and unhappy the first couple of days, he's now back to his normal self. However, he constantly scratches himself on one side and has now scratched a massive bald patch! I don't want to give up as it really does seem safer to have a reflective collar on in the long run but not sure whether to persevere or if it's really just not working. I can't see anything loose that could be irritating - is this just a stage to get through or do I need to take it off ASAP?
