ok yall so i have a standard chinchilla doe that is mainly a pet but we also raised a couple litters off of we got her 5 or 6 years ago and she was already 2-3 years then, i knew she was getting old but today when i went to feed her i noticed that she was barley using her back legs, i picked her up (which she hates) and her legs and hips felt so bony, i hadnt noticed it before because she is so fluffy, we will probably be putting her down but i just wanted some other opinions to make sure that this is due to old age
