Litter Box

I have a 2 year old female (spayed) cat. She has never had issues with not using the litter box before. I recently moved from a basement apartment to a 3 bedroom house with a full basement. Roxie's litter box is located in the basement. Lately she has been urinating outside the litter box. I have been cleaning these areas as soon as I see them, but I really need to find a way to stop this. I have been thinking that it is due to all the changes as of late; new house and new puppies (lab and weime pups). Thanks for any help

those are alot of changes for a cat. most would not handle that very well. Try adding a couple more litter boxes throughout the house. If you need to put up a baby gate so the puppies don't go litterbox shopping hehe. Make sure to show your cat where the boxes are and make sure that there are plenty of alone time places for her. (from the puppies) good luck
