The alternate version allows 10 pets but there is a problem with pets getting pregnant for a few people after having a certain ammount of pets in the family & I am still working on the problem.
Your welcome
I think its the same for the sims people cause I have 8 sims now and am trying like the dickens for a nineth and nothing.. I can't get the sim pregnant. but the try for baby option is there. I really hope this can be fixed. It would be a great mod
