and as far as can a black cat give birth to a white kitten...i believe so....if a black cat is white recessive Bw and mates with all dominant white cat ww it would look like this....potentially....

4 kittens options
Bw
Bw
ww
ww

so potentially you'd get a white kitten, but I don't know how to calculate in stripping (stripe not strip but i dont know which has 2 ts...i think im right lol)

i do know that they were worried that my baby girl had gone into heat when I had her spayed (which makes it an AWFUL HORRIBLE experience) b/c she was starting some of the signs (even "played around" a bit with dodger...whom had been neutered the previous month...THANK GOODNESS) but I got her to the vet in time and they said it was ok, but not to wait any longer.
