I got a new girl yesterday who is very verbal... She squeaks at my other rat often (mostly because the other rat is a young pipsqueak who likes to bug her to no end)... But she also frequently chatters and chirps. I noticed a bit of an odd noise she makes occasionally. Like a short high pitched "hoop" almost. Also sometimes while I'm petting her she will chirp or squeak. I can't always recreate it though. Does this sound like illness or injury? Or just new surroundings.
Thanks!
Thanks!
