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.

Life saver
My cat is 19 years old. She had gotten down to 1.78 pounds. After many visits to the vet and a bunch of pills and special food nothing was getting her to eat much or restore her weight.then I stumbled upon this at a local pet store. She now weights 2.81 pounds. This has been a life saver. She is much more happy, energetic, and loving. There are days she does like the smell, but more days that she will gobble. Thank you for saving my cat.

Life saving for my older cat hoppy
This stuff has saved our cat hoppys life. Every day he begs for it too, so it's easy to give to him and he loves it. He's one picky cat and this is his favorite thing to eat. It's a treat and gives him much needed calories.

I would much recommend this for older cats.. Hoppy is about 16

Great Stuff
I can not say enough about this product!! I have a 16 year old siamese. He has always been a thin cat, but was getting really skinny. I put the calorie booster on his food; his eating had reduced to 1/3 of a can of friskies 2X a day. The Calorie Booster has put a little weight on, his coat is shining, and he seems to have a little more energy.

a little while ago, my moms cat violet got sick and refused to eat. she was to the point when we needed to inject her with fluids the vet gave us cause she wouldn't drink either. it seemed so hopeless when she wouldn't even sit up anymore, we started thinking about putting her to sleep. but my dad bought this at a pet store and put about a teaspoon on his finger in front of her. she opened her eyes and sniffed once or twice then gobbled it right up! we gave her small amounts at first in fear of her barfing it up but she held it down fine! and she got better and back to her normal weight in under a month (SHE LOST ALOT BY THE WAY) yep this is a really great product!
