But for people who are giving their cat(s) an all meat diet definitely need to make sure they supplement the diet with calcium. And Yogurt and Cottage cheese won’t cover the calcium intake needed since they already have their source of phosphorus.
If the phosphorus isn’t balanced with calcium your cat’s body is going to have to get it somewhere which would be your cat bones. But, If your comfortable with feeding your cat bones along with the meat that’s fine, since bones = calcium. I just wanted to express that for the people who may not be aware of the damage it could cause i.e. bone deformities, limping, muscle failure, fractures if the appropriate phosphorus and calcium intake wasn’t supplied.
