Very broken hearted right now. Had to have my youngest guinea pig put to sleep today. I had 2 piggies and they were very close, bonded since they were babies. Kovu was nearly 4 and Oreo is 4 years 3 months. I need to make sure Oreo doesn't get depressed and lonely now. I've never had to deal with this before so could use some advice. I know sometimes the answer is a new piggy to bond with. I have made some enquiries today but not getting very far finding a suitable one.
