Strange questions I know but there are a lot of cat owners here and I would like your info. We have a male persian long hair cat who is almost 3 and a housecat who has supervised trips into the garden and no other cat contact, he seems to vomit nearly everyday, only at night and sometimes he brings up a hairball, the poor little guy will start to swallow intermittantly if awake then puke or if he is asleep he will wake and throw up, again this only seems to happen at night time. He is back and forth between the vet so we can find out what the problem is and taking anti hairball treatment and is back on dried food only with no treats, obviously the more it continues the more vet visits will be required which we dont have a problem with we just dont want to stress him out. Just wondered is anyone else has a similar problem ? when I lived at home the family cat used to yack everyday without fail and after numerous vet visits they never did find out what was wrong.
