All I want for Christmas is .... youuuuuuu!

Only kidding

All I want just now, hopefully well before Christmas, is for my cat to stop self harming
Aw, poor wee cat. Something must be bothering him/her.
We tried Feliway spray from Pets at home and it did seem to help.
Thomas had been through a lot when we got him from the rescue centre. He was settling in then our neighbours cat began terrorising him, beat him up then began throwing herself against our windows if she saw him inside. He began showing some stress behaviour and the spray did help.
Happily his confidence grew, decided he'd had enough and gave his assailant a "do in" and she's never bothered him since.
He was at vet for his booster last week and hid at top of wardrobe for 2 days after, silly boy!
Hope you can figure out what's causing this and help the little one, best of luck.
