I hear that cats tend to vomit a lot and sometimes for reasons that are not serious. That said, two times in the past day, we have found cat vomit on the livingroom floor. We have not witnessed the vomiting so we cannot be 100% sure of who is doing it. I suspect that it is Beowulf, though, because I found him near the first pile of vomit last night. Of course, it could be both of them.
So what do I do? Is this a "rush them to the vet" moment or a "wait and see" situation? I'm not one of those people who goes to the vet as a last resort, but I can't afford to be one who rushes to the vet every week. We've had the boys for 4 weeks and been to vets about 5 times (some for vaccinations, but still). The time when we most thought we had an emergency was when Arthur's eye got swollen, but after going to the emergency vet and not being seen, his eye was almost 100% better by the time we took him to the regular vet the next day.
At present, neither cat appears ill, though I have seen that Arthur is eating more wet food than Beowulf of late. Both incidents of vomiting occurred during "free feeding" time, meaning the boys had had dry food available to snack on. I believe that Beowulf had just eaten a few pieces of kibble before his incident last night.
They are eating the same brand and type of dry food on the same schedule. Ditto for their wet food. Now I hear that eating too fast can cause vomiting and so can competition for food (Arthur is hogging up the food a bit). True, this hasn't happened before, but we've only had the boys for a month and they are growing up and sorting out their hierchy.
