The cage is to help the cats realize that peeing OUTSIDE of their litter boxes is a NO-NO. The finding of blood in the urine tells me that this is at least partly medical, but I believe that it is still ALSO behavioral. After all, Jim sprayed ME!!! and if that wasn't claiming property than what is? And Sterling, plays rough, like he is always trying to dominate the other cats, and since it was combined with spraying, I want to make SURE they know what is expected of them.
The cages are tall cat cages, big enough for vertical space via shelves. They have a litter box in with them. And I bought them each a nice new rug to use as a bed along with a water dish that can be attached to the cage so they will not spill it. They need not to soil their area before they go on to a larger area and then on the the whole house.
The anitibiotics should take care of teh infection, hopefully. They will be retested in 2 weeks. The other medicine should calm their stress level. In other words, they should no longer have hte urge to claim thing as their own propery.

Truth be known, I have not been home since I caged them. (went to my dad's house). I am kinda apprehensive about being there with them all caged up. But I am on my way home soon.
