I've had Bramble two months today. Her cage had a small reshuffle yesterday. She was acting really unsettled, climbing the bars and trying to squeeze through them. I don't know if it's because winter is coming, but she suddenly felt need to create a huge burrow and hoard lots of food, but the megazorb I was using wasn't holding her tunnels up. I switched her onto Fitch and she's already so much happier. I can hear her scrabbling around under the substrate now.
I have never known an animal to be so laid back. Literally nothing scares or alarms her. The gerbils are jumpy from the fireworks tonight but Bramble isn't bothered as usual.
