My name is Chesterfield!

We’ve had Chesterfield for 8 years and he is really an affectionate cat. We recently relocated with work, and had to move from a big house on a quiet street with a big yard into a small condo on a Main Street. He needs to be able to go outside and roam and hunt for mice, but he can’t do that here. He has had urinary tract issues, so he is litter trained, but also has problems where he often pees out of the box around the box. He does great outdoor/indoor, but is struggling just staying indoors.
