Our cat is now completely on a wet food diet. We switched him in order to help him lose weight and it has really helped. Was wondering if anyone mixes in some dry food as well? We are concerned about his teeth. Also, would like to have the option of dry food for when we are away overnight (currently we feed him 3 times per day and we are not supposed to leave the wet food out for more then 4 hours). Advice would be appreciated.....
