Before anyone jumps to conclusions, I do NOT offer bugs or any other animal protein to my Russian Tortoise. That noted, I have caught him a few times purposely chasing grasshoppers, crickets, large ants, anything he can see. On occasion, I've seen him catch them and start eating them. (I bred crickets and roaches for bearded dragons for a few years. They've found their way into other enclosures here and there).My question is, is this normal? Is he that territorial that he feels the need to murder any living creature in his territory and NOT just my toes and feet? It hasn't hurt him over the years on the rare occasion it's happened, just curious if anyone else has had theirs do this.
