sorry for yet another vomiting post but there is a particular pattern of my cat's behaviour that i hope someone might be able to shed some light on. Over the last 3 weeks, every few days my 5 year old persian will use the litter tray and her poo will be fine. she will then come back in a few minutes and it will be much more liquid and then she will immediately vomit up some bile. there is sometimes some blood in the vomit and the diarhhoea. my vet doesn't seem too bothered as she will recover and act normally after a few hours so he doesn't think i should be too worried but whilst she often vomited up bile in the past, she has never got into such a definite pattern. i haven't changed her food - she's on purina pro plan and a bit of wet food each day. the only change is that she seems to be catching more mice type animals but doesn't eat them. Anyone have any ideas??
