I shed a few tears for your kitty. :(
One of the strongest paranormal experiences I ever had was feeling a kitty (that wasn't there) jump on the bed and walk over and snuggle up next to me. At first I thought one of my cats had jumped on the bed, I was certain of it. Then I looked down, saw no cat was there, but yet felt the last few footsteps and the snuggling up. My wife had independently and unbeknownst to me experienced the same thing. These events happened shortly after losing her most beloved kitty of her life named Buzzy and stopped after getting a new kitty that looked and acted very much like him named Stripe...
