I groomed my long hair cat last week (he doesn't need it often, he doesn't get knotty, I just do it every month or so to stop the shedding) and today and yesterday he has been being sick with a lot of fur in it. He seems ok in himself but he isn't eating much and the bit of tuna I gave him earlier has mostly come up. HUsband is away on business and I have two small toddlers so getting to the vet is going to be tricky, what should I look out for to say he needs to be seen? He is drinking a little water and eating tiny amounts. The sick is quite yellow but small quantity, couldn't tell you about his bowel movements, he goes out for that.
