I have an ancient Abyssinian Guinea pig that I got from the RSPCA almost 4 years ago. I think he's 5 or 6. He's always had issues as he has a prolapsed penis from his nurturing surgery so needs a lot of extra washing. He had an eye injury a couple of years ago so was blind in that eye but he's slowly developed cataracts in the other eye and I think he's almost blind now, he's also very very thin under all the fur. He's still bright and eating and toilets my well and he loves company but I think he's reaching the end.
Has anyone ever had a GP put to sleep instead of letting them gradually fade away? I don't know what's for the best.
