So this is the second time in the past month that schnitzel has aggressively bit me but this time he got my palm and it is swollen and hurts like a mother....I am long over due for a tetanus shot and have had a few people mention I should get one because he keeps biting me.....He desperately needs a neuter that we can't afford right now so what do I do with him? should I stop letting him have free time since that is when he bites me when I go to put him back in his cage or start picking him up with a towel or something?
