I'm thinking of trying to create new wall shelving which combines storage and desk space with shelves for the cats to climb and explore. They tolerate each other but are not bonded and sometimes have little spats, so I want to ensure they feel that they can each escape to their own space as well as using up energy and having more stimulation. I'd welcome any ideas for using wall space in this way, and also any other suggestions for enriching their lives in a small indoor space.
We've been living temporarily in two small rooms for two months now, and they've both visibly put on weight (neither have had weight issues in the past; last winter I took one of them for a vet check as she was looking so skinny that I was worried that she might have a thyroid problem, but apart from a 'slight heart murmur' she was declared in good health for her age). Now I'm concerned they're going to become little furry barrels if I'm not careful

Any advice to help with this transition will be much appreciated.
