Had 2girls and found one passed away this morning and I dont know why. We had them given to us so no idea how old they were. They were outside in their hutch I didnt think it would be too cold the hutch is in a corner out of draughts plenty of hay to snuggle in. They both seemed healthy no mites or lumps. Coats were full and thick. They were eating well etc. Any ideas why one would just die? How do can you tell if its just one of those things or if I did something wrpng?
They can just "go" Mollymum sometimes as quick as you describe. Eating and poohing, then gone. If they are ill though they hide it well. (One of my boars died in July, he went very quickly, but I saw the "signs" and took him to the vet. Piggy was beyond it though)
When I was a child I had loads of piggies, most would become ill and go within 24 hours ( floppy, rubbery body, backbone seems like there's no support. Sometimes they get tucked up and starey coated)
But 2 of them just went - fine one day, then we found them. (Evil Edna died in a blaze of glory, lying in the middle of the dining room floor . No hiding away for Edna)
You've now got the situation of a lone pig. Keep a close check on her, make sure she's still eating. Good idea to go through the cage, take everything out and scrub or steam it, just to be on the safe side.
We had this with one of our (young) piggies back in June. All seemed fine, then she just suddenly started squeaking a lot, and collapsed. I'm guessing probably a heart attack. Poor DD1 still hasn't really go over it .
Only thing I know about g pigs is that need fresh greens daily as they can't synthesize vitamin c. Not loads, and not lettuce as it can give them diarrhea, but a bit of cabbage, apple or carrot for example. Sometimes these things just happen.
One other thing I remembered, have you looked at their front teeth? Maybe they were overgrown and not meeting properly, pigs would look thin and unhealthy if this was the case though.
