I've had my 2 Guinea pigs for 4.5 years, they're litter mates and are identical. Ginger has been plagued with health problems for a couple of years, with a cataract and lumps. She was given a couple of weeks to live last week as she has inoperable tumours. Ninja has always been healthy, nothing wrong with her.
Ninja died today. She ran across the cage, then sort of fell down and started twitching. 15 minutes later, while we were waiting to see the emergency vet, she died.
I don't really know what to do now. I'm heartbroken ðŸ˜. I've left her in the cage so her sister can say goodbye, but she's ignoring her completely.
