My old childhood cat was very lethargic, on her last legs, barely moving, and not eating, so my parents rushed her to the vets on a Saturday.

Conclusion, sore throat.
Medication, cat painkiller.

Now she's fine.

My pup was shivering, upset, very in pain. Got him to the vet. He was howling, making noises I've never heard him make before. I literally thought he was dying.

Turns out he had gas. Vet had us pick up baby gasx. One big poop later and he was fine.

Hi i have his brother, the tiny ginger shit who ate an entire packet of freeze dried chicken, could not stop vomiting, emergency vet run where there was a rush on, he was hooked up to monitoring and fell asleep while we waited, two hours later woke up, let out a HUGE fart and was fine.
