I have two cats who sadly don't get along - had them for 10 years and they mainly ignore each other and now and again fight, which mainly consists of sound and fury and not a lot else. Never been any injuries or blood drawn. It's a female torbie and ginger tom.
Tonight they had one of their spats which ended with the ginger making an awful noise like we rarely hear. The kind of growling they do when something unusual is happening or something's wrong. He lost control of his bowels on the stairs, which he's never done, then came in the kitchen panting with his lips dawn back. He's just gone to lie on the grass and is panting less but just seems shaken. No wounds that I can see but tongue sticking out a bit still. Do I need the emergency vet? I'm leaning towards yes.
