I've had Bella almost a year now and the last couple of days she's been acting really weird. She has slept in her see saw instead of her house, and she keeps chewing at everything when she would normally be asleep. Im not sure why her behaviour has changed. She's eating normally as far as i can tell. She just keeps going back into the see saw and scrabbling around and then falling asleep. Then she wanders around the cage a bit and then goes back to the see saw or starts scrabbling again. Any idea why she does this?
