I ordered this for my 3 cats. I have one with skin allergies, one with a heart murmur, and one who just eats way more than needed. Since I started putting this on their food I've noticed an improvement in all 3. Their coats are shinier. In fact, my one with skin allergies is finally growing a full coat back! So far, I'm happy with the results!
Bottom Line: Yes, I would recommend this to a friend
