I have all of my chins on Mazuri and they get 1 or 2 raisins a day plus Hay. I do not give them any other treats since this is what they are used to and they enjoy it a great deal. All of my other chins are healthy, happy and active. (I have 5 plus the ladies 4)
The lady who owned the 4 males and the dead female gave them stuff (cr@p excuse my language) like Pizza crest, breads, cookies or whatever. I'm honestly surprised that they have lived this long after eating like that with her. The actually non people food that she gave them was guinea pig food from walmart with the mixture of bananas or something. You know the cheap stuff, not just pellets. Since they have been with me, I was mixing my mazuri with very little of her stuff and then totally switched to mazuri once they were eating it. I did this to avoid problems with their digestive systems. They now get Mazuri, hay and 1 raisin each. Thats it. The longer they are in my household, the more active they have become which is a good sign but I also know it will take awhile before they are truly healthy providing her "care" did not do to much damage.
On a much happier note. My standard grey had 1 kit this morning. Both seem happy and the kit is very active already. This is my standards 3rd litter which she keeps having while I am sleeping. haha
