My eight year old cat has started digging her claws into my clothes, putting her paws on my face with the claws out , using her claws on everything. She never used to do this. She is making holes in my clothes and it hurts. She has also started to bite us sometimes if we stroke her in a way she doesn’t like. I remove her claws and tell her ‘no claws’. She does seem to get it sometimes but the claws are still coming out .Why would she start doing this all of a sudden?
