They are not easy to housebreak. All three of my furbutts are now 2 years old and although I have 2 that are 100% trained I still have the 1 which is my rescue that will have her little accidents here and there but she's gotten better. Her problem is that she doesn't like when you watch her so if you're near their potty area she will go elsewhere and do her business. Also she pee's on herself when she's very excited and she doesn't get in trouble for that. Its really not her fault. Thank goodness for hardwood floors and ceramic tile
