Nice pix, he LOOKS so sweet! He obviously loves you, or at least the grub he steals from your dogs!
We are blessed with a pair of very well behaved Ocicats, never get a chance to bring us dead wildlife as they are totally indoor kitties. They are absolute joys and we love them to pieces! Ours rule our home with iron paws, but lovingly!
There are a few general rules for you to keep in mind to insure you have a proper relationship with felines:
1. Dogs have owners, cats have staffs.
2. Thousands of years ago cats were worshiped as gods. To this day they have not forgotten this fact.
About kitty getting in through the doggie door to pig out: Assuming you want to prevent this, there is a possible solution for you. There are doggie doors available that will only open when triggered by an RFID device either worn on your pet's collar or some will trigger off a microchip if your pet has one embedded. No RFID/microchip, the door won't open.
