I agree that the male should be neutered soon before any bad habbits develope. Even if your female is to small for him to actually mate (which I'm not saying is the case, I think they find a way)

The males do get very determined and may be alittle ruffer with her than normal. She's so small that she could become injured. It's very hard controlling a male and I wouldn't take the chance...I'd suggest, make the appt. soon!!
