Yes my male cat is nutered. He often chases Sammy around and wrestles her, licks her in her private area and who knows what. He did that before she was pregnant and even now that she is pregnant.

Do you guys think it would be a good idea if I seperate the two, given the fact that Sammy is pregnant and Herc(male cat) always chases are around and could cause her to miscarry?

how should i go about this situation?
