Have Cat Questions? Ask a Cat Vet Online.
Hello,Thank you for using Just Answer. My name is***** am a veterinarian and will do my best to help.
I am sorry to hear you are worried about Madison losing weight.
You can feed these products, but if she is lactose intolerant as some cats are, it might cause gas and diarrhea.
When I want a cat to gain weight, I try giving her canned kitten food, or one of the high calorie diets made for cats like Recovery (Royal Canin) or A/D (Hills). These are sold by veterinarians only.
These milk products are balanced for human infants, and would not have the nutrition that a cat needs.
If she is losing weight, I would also consider trying to find the underlying reason for her weight loss, such as kidney disease, heart disease, hyperthyroidism.
I hope you were able to see my responses! I have not heard back from you.
