One of my good friends is a top Persian cat breeder. We get all of our cats from her. As with a lot of older folks, our fur babies are treated as honored members of the family. They treat us as staff, as the old line goes. Nothing is too good to keep them in tip top shape. I do a basic "recipe" that they have eaten their entire lives. It has raw hamburger, egg yolks (cats can't digest the white), Wellness chicken cat food, vitamins/minerals and V-8 juice. While my friend mixes it up "fresh" for her cats (she has a lot more), I usually do a two can recipe and freeze it it smaller packages to defrost as need be for our two cats. They like it a lot. It subsidizes their dry food. One of our cats turned 16 years old in May and the other was 11. They always get great checkups, so it must be working.
