today my oldest kitty had some type of episode that had him staggering. We took him to the vet and he seems OK but they want to check his kidneys and such. The odd thing is, it was the same room where his sister passed. When we went in that room he started to purr. He knew. he misses her as much as we do. PJ is on his way, but like all cats, he will come to you when he is ready. Stuborn little cuties.
