Cat to rehome

Reaper needs a special home where he is the only animal... he is a very territorial cat and we have done everything we can to not make it an issue but it just isnt working... hes very lovable likes to explore outside in the back yard but is an inside kitty... hes on special urinary hydrolized food from the vet... he is neutered... please let me know if you can give our guy a loving home... will add pics in near future
