<human>: Hey y'all,

As a preface - I've taken my cat to the vet about regular vomiting at least 6 times and they have basically concluded I probably just have a chronic vomiting cat.

My cat has been otherwise happy, healthy, active with regular appetite and litterbox use, but would vomit almost daily. Even if he didn't eat anything it'd be clear (bile maybe?) or sometimes with food in it. However in the past few weeks it's now become dark brown, very forceful (it splashes everywhere) and reeks. Google tells me this may be intestinal blockage but as you can imagine I'm reluctant to take my cat back to the vet for the 8th or 9th time to be told "it's a mystery, maybe he's just like that" again. I've taken him to 3 different vets and nobody has been able to help the little guy, but now the vomit is worse. Any input appreciated.

Can you provide a brief overview of the text?
<bot>: cat that vomits all the time "normally" (yes I know that's not normal) has started vomiting forceful, splashy, dark brown, hideous smelling vomit. Any hints as to what might be causing this?
