My cat had kittens 3 weeks ago. I just got my male cat neutered today and have had him crated at night for these last 3 weeks to keep him away from the mama. Unfortunately, we were traveling about 2 weeks ago and he did have access to her for about 2 ro 3 days. There was nothing I could do to keep them seperate due to the circumstances. I have noticed that she has not lost her "fat" since giving birth and I felt her abdomin today and noticed a small lump. Obviously there would be no way to tell outwardly if she was pregnant and I was wondering if that lump(I didn't check for more) could be a kitten. It was oval shaped and about 1-1 1/2 inches long and about 1/2 inch wide. Is she pregnant again or is is just her intestines or something???Please help.
