Thank you for all the advice!
I did have to put down on the application that I had a cat and then I didn't have Lilly at the time and so I did tell her I have an 11 week old puppy now too. She did suggest putting her in a room by herself, which I have a spare bedroom they are going to stay in, in a pen and the door shut. My cat's box and food and water bowls are in my bedroom. Lilly has the bathroom. I don't intend to let them around momma and babies much at all and not at all at first.
I've never had a momma dog and puppies. I have had plenty of momma cats and babies, so this will be a new experience for me. Looking forward to it.
I also start a new job on Monday so I have a very full plate. LOL
