I didn't know pets could forget you! I left my birds last year when we went on vacation for more than a month and when we returned they were sooooooooo happy! They kept giving us kisses and snuggling with us and refusing to get off our shoulders! I think your cat will remember you again but my birds never forgot me! In fact, they miss me so much when we go on vacation that they look thin when we return! Then when they come home they get happy and start eating well again, and soon become their chubby cute selves!
