Thank you for the suggestions. I want to get something soon, so I can work on him learning to use it, before we actually go somewhere. This guy was 11 when we got him last summer. Since then he developed glaucoma and now heart issues. I really want to take him on some trips before something happens. He's never been in the MH, so I'm planning on taking him along when the weather breaks and I go out to tear everything apart and clean to get it ready to go again. Amazing how fast these little fur kids worm their way into our hearts. When his heart issue surfaced a month ago, I about lost my cool. Not ready to lose him yet -- not that I will EVER be ready. One day at a time and every day is a gift.
