I have own red eyes for 3 years now and unfortunately, I just recently lost my male. I never intended to breed and they were just my pets, so this is just about the happiness of my female frog. Should I buy another frog? My female seems kind of sad, not sick or anything, but she doesn't chirp as much anymore and she isn't as active. I have checked her out and she is in good health, so I wonder if she is just lonely. Anyone have any advise?
