My cat has suddenly decided that his tail is not a part of him. He catches sight of it, goes completely still and watches it for a second, then runs off and hides. After doing this several times he starts attacking it while hissing, biting and growling - it’s actually terrifying. Has anyone else ever had this problem? If so, what was it? Got him a vet appointment but it’s not until after new year. Google searching led me to fleas - but he’s sitting watching it and trying to run off before attaching so not sure that’s it!
