My cat vomited, now breathing heavy, weak, and pooping himself?
Hello and welcome to Petco Pet Education Center, formerly Petcoach. Sometimes when we, or animals, vomit, as cats sometimes do with hairballs, this can put pressure on a nerve that runs through the stomach that can cause us to become weak and defecate due to changes in blood pressure. If this was the case then Blaze should have returned to normally very quickly after the episode and be 100% normal now. The other possible cause is that Blaze could have an underlying heart condition that is causing a weakness, or could have aspirated (some of the vomit went into his lungs). If Blaze is still breathing up, or acting abnormally, or if the collapse episodes occur again, I would have him into the vet right away. If he is completely normal now then I would just monitor him and have your vet check out Blaze's heart at your next exam for vaccines. Best of luck with Blaze.
