We have a cat. She has a cat door so she can come and go as she pleases.
It seems another cat has decided that it can come in and eat her food. The cat door is right next to the laundry where her food bowl is. It seems to be happening more and more now. I have caught it racing out the door when I have arrived home and her bowl has been licked clean twice already today (she never licks it clean). It tends to come in when we are out, but I have also heard the cat door going when my cat is in bed next to me.
I can't think of anywhere else suitable to put her food and I would rather not shut the cat door because she is old and it is cold outside. Can anyone think of any way to stop the other cat from coming around? Do you think if I shut the laundry door and it couldn't get to the food for a few days that it would give up?
