I sympathize with taking care of sick animals (are as I call them my kids). Have you ever sprinkled yeast on there food? My cousin does this with her cats and dogs, it helps them and her cats LOVE IT! It's good for them. There are also vitamins you can give them. I give my dogs some human vitamins and they really work. There is some other stuff my cousin does, and I can ask if you would like. Hope they get better soon.....
