So of course, it's early Sunday morning in a small rural town with no emergency vet...and I might be over-reacting anyway. My little Maisie, about 6-7 months old and normally bursting with life and joy, has been off-colour for the last 18 hours or so. Vomited once, then became floppy and lethargic, very sleepy, i sat up part of the night with her, and she was grinding her teeth and with a long drool coming from her mouth. Refusing food and water, but has just got up and used her litter tray- a good-sized wee, first in 18 hours, now lying down again. Doing her best to purr on stroking. i wondered at first whether she might have been poisoned, but there was only the one vomit. Now I'm thinking constipated as her tummy is quite distended. Can any kind person think of anything else it might be? Thank you so much.
