I want to feed my catfish frozen-thawed mice (like the ones for snakes). I am going to be completely honest, I don't want to do this for any nutritional reasons at all, I want to do this purely for the shock value of seeing my fish eat a mouse. Is this safe? Will the fur and bones clog up it's digestive system? I am guessing it's not because I feed him fish with scales that are also make of keratin, and I've fed him pieces of fish meat with much bigger bones... What do you guys think?
