Cats don’t cuddle anymore 😭

My cats are a bonded pair from a litter and are just over two years old. They used to cuddle all the time! Like multiple times a day I would find them in a pile and it melted my heart.

And then about a month and a half ago I took the boy Malcolm to the vet and learned my lesson because the girl Matilda was a total brat to him for almost two weeks. The hissing has finally stopped for the most part, but they don’t cuddle anymore. Malcolm will come up and start grooming her and she’ll start biting at him shortly after and it turns into a wrestling match.

Any thoughts on how to get Matilda to stop biting at her brother when all the poor guy wants to do is groom her and cuddle. 🥺
