Ok so for some reason my redfoot would just bite at the substrate and start to swallow sometimes. What's the problem? I feed him each day and he has 2 bowls of water so if one gets dirty in the point of the day he can use the other one. It's been bugging me because I don't want him to choke. Also the substrate is cypress and the ends seems harmful if he swallows it since it's pointy but not like pointy pointy just like normal pointy. please help! I'm worried!
