A few nights this week I have noticed my cat foods dish to be empty in the morning. I found that odd. Turns out last night I heard a cat eating and it wasnt mine because she was in bed with me. It was strange because my cat didnt even do anything. I jumped out of in bed in time to hear the cat door slam closed and the culprit was gone. What can i do to avoid unwanted animals. I know I can get a magnet door and collar for my cat but it worries me to put a collar on my cat, she is so active climbing trees and such I am afraid she may catch it on something. I was wondering if there was anyone else with this problem that tried something that worked to eliminate this ... I like cats but it makes me angry. Now i am wondering if it was my cat or this cat that made a mess of my place the other day! and here i thought it was my cat who i thought had an upset stomach. Help!!
