My cat loves it!
I have a cat that is very finicky, but she really likes this. I give it to her for a supplement and I like it has vitamins in it.

This has been a lifesaver with my 16-year-old cat. She'll only eat it from my fingers, but she has hyperthyroidism and lost a lot of weight. This is a great supplement for her.

Great product that my kitty loves
I bought this for my cat that needs meds 3 times a day. She is terrible at taking pills but she loves the taste of this so it makes pill time not stressful. I bought a cheaper version off amazon and it was a disaster. My cat was hiding and spitting the meds out. The other brand was sticky and messy. So I quick bought this again and I have a happy and unstressed kitty again. I first came across this at Petsmart because I was trying everything to hide her pills in and thought well she needs to put some weight on anyways. It has made her keep eating so that's a plus and she's maintain a healthy weight. She was a little underweight after she starting having medical problems.

Great product
Great product. Was gonna use it for a sickly kitten, but he passed before the product arrived (not the sellers fault, he was just to sick to hold on) but the other cats scarf it down.

Finicky cat loves it
My thin little Siamese loves this. He can not have anything fish flavor due to allergies so it was wonderful to find this product.

Kitty Grows up with this
Our Kitka came to our house when my daughter found her lying in a gutter. She was very small, starving and full of fleas. She brought the kitten to me and we did all the usual things to save her. We feed her milk replacer every 2 hours. After 3 weeks she was holding on but not really thriving or growing. I picked this product up and thought "Well we have nothing to lose." She loved her treat and immediately started to have more energy. In a week I could tell she was finally growing. She is 12 years old now and this is still her favorite treat. I think it helps keep her healthy because she is a very picky eater.

Kitten is finally growing!!!
When I got my kitten at 8 weeks, he weighed 3/4 a pound - the vet was not happy!!! At 5 months, BabyKat weighed 3.4 pounds. I found this product at a pet supply store in Richmond. I squeeze a circle of this on his dry food and he loves it. He has been eating this for approximately three weeks and is now growing...and has gained a full pound! Highly recommend this product.

Why would you load a product with so much sugar? It has sugar, malt syrup etc etc. in it. Have you heard of diabetes in cats? I am worried feeding it to my 18 year old cat. Please explain why I should not worry.

BEST ANSWER: This isnt made to use every day. This is to help cats who need a vitamin boost. It helped our kitten who was very lethargic and missing nutrients. Only used for a week, 2 at max.
I'd like to buy this for my 15 year old guy. His kidneys are an issue and he has to eat special food. Will this be ok for him?
A shopper on Jun 11, 2013
BEST ANSWER: Absolutely! That is what this product was made for; older kitties, sick kitties, and any kitty who's off his food or needs a nutritional "kickstart". This product is very mild so it won't upset his tummy and tastes great so your little guy will look forward to getting it. :)
Can you make this in a salmon flavor as well?
