1. Never leave food outside, as it attracts raccoons. Neighbors error, big time!
2. The solution: neighbor gets dog and feeds the cat indoors.
3. Your cat goes elsewhere for excitement. Unfortunately this may incur expensive veterinary bills on your part.
4. The solution: keep you cat at home. A cat climbing gym and another feline will make him interested in staying home.
I have five cats and have been a cat owner for 57 years.
