I have an 8 yr old female (retired breeder) and a newly rescued 5 yr old male. They both pee in their crates, even when I am just gone for a couple of hours. I have reduced the crates' sizes, wash their bedding daily, wipe down with enzymes cleaner, no water after 7:00 p.m. or so, plus plenty of potty trips prior to my leaving. Both are neutered/spayed. Any other suggestions??
