My 13 year old cat is extremely picky. I have never been able to use any kind of supplements as he refused them. He immediately accepted and loves Nutra Thrive, he now eats all his breakfast with enthusiasm. He is shedding less, his bad breath issue has completely resolved, and hasn't been throwing up or had any hairball issues ever since beginning this regimen. This product is a real WINNER in this household! I would recommend this product to any cat lover, you can't go wrong!
