How can cat spray odor be removed from painted walls and varnished furniture?

Care for 40 'fixed' kitties; have 10 litter pans which are cleaned at least once daily, plus a large outdoor caged area. They have sprayed every wall and furniture surface in the house. The walls and furniture are sprayed down with enzyme cleaner weekly. The water-based paint on walls is bubbling, we don't know if from urine, enzymes, or both. The varnished wood furniture is swelling, rusting, etc. All the cats are in good medical condition. We can not get the urine odor out of the wall paint. Would applying Kilz then repainting with oil-base paint help the situation? How can we 'unswell' wood and veneer finishes? Any serious replies appreciated. (We know all the insulting, funny, and kinky ones, thank you).How can cat spray odor be removed from painted walls and varnished furniture?
The swollen wood and peeling veneer are toast.





Kilz is really meant to stop resin from coming through. Who knows what it would do about odor?





My guess would be that the problem is overcrowding. I know that you can really pack a lot of cats into a small space, but I think there must be consequences to that. I would guess that the problem is feline sociology, not feline scent.





I bet you rescue strays. Some of your strays were probably toms with well-established spray habits. I'm not optimistic about your being able to fix this problem without training specific cats.How can cat spray odor be removed from painted walls and varnished furniture?
