Maybe, but she is really territorial! She still attacks the bars when she senses another chinchilla nearby but when they're not she just acts depressed. It's the only time I see any real activity out of her, she doesn't run and jump like a "normal" chinchilla and she doesn't get into mischief like a normal chinchilla either. Now that's a sure sign of depression in a chin!
Ooh, she just jumped up on the toilet! That's the highest I've seen her jump since I brought her home. That's a good sign
Hopefully once she lets go of her partner she'll be able to accept other chinchillas. That's what happened with Pippa. For the longest time she remembered her sister's name even and I couldn't mention it without her stopping whatever she was doing and looking around for her
