my cat is about 10 years old, hasn't had any problems thus far but for a week now she hasn't been eating properly, she's just eating very little amounts of supermeat catfood and when she eats she seems to be having problems chewing as she starts acting as if the food is getting stuck in her mouth and then she'll spit it out. she used to love her cat biscuits but she doesn't seem to be to eat them at all at the mo just spits them out too. she's acting completely normal and fine apart from this and still has appetite for food as she's going over to it. she's also been being sick every day, she's been bringing up little amounts of white bile but this seems to be getting less frequent now. my mother gave her some cream a week ago and these problems started since then and have read that dairy products can cause problems in some cats as cats can also be lactose intolerant, just wondering if anyone can shed any light on it, should i be worried?
