When is it safe to let the dad around the kittens?
It depends how he acts. I would supervise him around them for a few days. Cats are instinctively 'wired' not to harm small kittens. When they do, it is usually not their kittens, but some other toms'. Most 'dads' are fine, just curious, and mom will protect them. Just make sure it doesn't stress mom out too much and that he is not stressed either.
If he and momma are friendly with each other, and momma is OK with him being near, you can prob do it very early; superwised at first of course.When is it safe to let the dad around the kittens?
