My squirrel bites when hungry

[Roky's mom]

My squirrel bites when he is hungry. Is that normal and any other advice would help.

How old is he?

[Roky's mom]

He is 6 to 9 months.

His name is Riley and his sister's name is Elisabeth. Could it have something to do with them being in the same cage together?

They're coming to the sexual maturity stage and are probably wilding up. Are you planning on releasing?
