"I originally began using this product as a nutritional supplement for my severely underweight shelter cat. Now that his weight has stabilized, I use it as an extra-special treat because he absolutely ADORES it. With Nutri-Cal as a reward, he'll happily sit still while I trim his nails, and he purrs and drools the whole time because he knows the Nutri-Cal comes at the end of it. It must be yummy!"
