I’ve just arrived from the Vet and I’m a bit concerned and don’t really know how to solve this situation.

I have a pet Gorilla, his name is Marv. He’s the most gentle creature you’ll ever encounter.

However, in the past three months, things have changed drastically. He started to become violent but only for 4 days out of the month. He starts by getting very restless, pacing and requiring a lot more time to fall asleep. Sometimes he has tantrums and breaks some stuff around the house. This month he broke the arm of my favourite chair, so I thought it was time I’d take him to the Vet to see what we could do about his behaviour. I’ll do anything that might get him to be the nice and loving Gorilla he used to be.
