What is the difference between the cat version and the kitten version?
Answer by ChewyJul 12, 2020
This kitten supplement contains 25 calories per teaspoon and the "Tomlyn Nutri-Cal High-Calorie Dietary Cat Supplement" is formulated for adult cats and contains 28 calories per teaspoon.

I need something to mix with food as my kitten dose not go for wet food any more like she used to. She is 6 months not to skinny but not really gaining weight. Can I mix this in her food?
Answer by ChewyMar 28, 2018
To supplement your kitten's caloric or nutritional intake feel 1/2 teaspoon daily into orally. To acquaint your kitten with the flavor, place a small amount of the gel on its nose or in its mouth.

Do I need a prescription to purchase this?
Answer by ChewyFeb 13, 2020
This supplement can be purchased without a prescription.

How old does a kitten have to be? Is there an age limit?
Answer by ChewyMay 17, 2019
This supplement is recommended for all kittens.

Runs for the cover of the bed

I really don't like this product. My mommy keeps trying me to take some and she gets it on the paw or nose. Now, I am hissing at her- which I do not want to do- but she got to understand I don't like this gel. Sorry mom, but I am a lover not an eater. Yes, I am a skinny cat- get over it. Captain Morgan

Good stuff for an underweight kitten

So I had a rescue kitten in a failure to thrive situation. I got him this to help put weight on him and hopefully give him an extra boost. This and the Acana food have been lifesavers! The kitten has finally put on weight and has more energy than I’ve ever seen! I honestly wondered if he would make it. Been a hard month. He’s all over the place now, which is amazing <3 Only downside is this little guy is picky! He won’t eat it on his own. So I put it on my fingertip, give him a quick neck scruff like the vet does, and down it goes. Not a huge deal to help facilitate that he get this good stuff in him. I would recommend this to anyone with a cat that is struggling.

Cats won't touch it

Only 1 of my 4 cats will eat this, though 3 of them will eat the regular malt flavor. My older boy won't eat either flavor and he's the one who really needs it.

My eldest loves it

I’ve been buying this since my oldest boy was 14. I also give him the laxative in this brand once he starts vomiting. He used to eat the laxative like he liked it until I started him on this. Which he still eats it when needed but it’s clear to me he really is bit disappointed when he realizes it’s not this. He is 16 now. I love it. Let me be clear though. Just because my cat adores it doesn’t mean your cat is going to. I have a younger one that when she needed it she wouldn’t touch it. I have another one that should she catch me giving it she has to have a bit of it as well. She loves it. I found when I give it in little bites throughout the day as opposed to one dose it stimulates his appetite and he eats better. He has actually put on more weight since I started doing that and I supplement him with wet and share some chicken. He lost appetite and has trouble eating dry food now so this combined with soft foods is fantastic for a senior cat! Love this product!

Works great!

I’ve been fostering kittens for a long time and love this product. I typically mix it in their wet food but I’ve also given it by mouth without any issues

Not super palatable

I bought this because I took in 9 kittens from a hoarding situation. Two of my boys came really emaciated, so I wanted to boost their caloric intake. My oldest forcefully spit it out and tried frothing at the mouth. My tiniest one wasn’t the biggest fan either. To me, it smells like corn syrup rather than fish so I don’t blame them for not liking it. In the future I might mix tuna juice in it to make it more yummy.

kitten loves it!!!

My kitten wasn’t eating much she was very skinny, when I bought this i started giving some to her once a day and now shes eating more than ever!! This really works if you have a kitten that is a picky eater or a kitten thats skinny and needs nutrients!

Yummy! Mom knows best

My mom gives me a fingertip of this at least twice a day. She says it’s because of all the good nutritional ingredients but I love it because to tastes so good! She adopted me and thinks I was probably a feral kitten without any good meals. This is a great supplement to my meals so I’m really thriving!

Cats sudden demise on the mend!

Our beloved baby (4 yrs old) started getting lethargic and felt deathly thin. Rushed him to the vet, went through a battery of tests found out its a UTI. He got an antibiotic shot and a cortisone shot. Vet said to still watch him. Well watching wasn't going to get him back on track I needed to build him up! He was so weak and fading in our arms it felt like... So I thought well hey what do they give kittens they find off the streets and they save them?? So I found this. He is not 100% but he is definitely on the mend and playing and his coat is just gorgeous. I am still working on his weight. He doesn't like the gel in his mouth. I've had to give it to him on his paw to lick off. He's not happy with me about that either, but I am desperate to get his health back. ***If you do NOT know (I did NOT) LILLIIES ARE FATAL TO CATS.*** Lillies were in a bouquet on the floor of the room he was in!! I don't think this helped him any but I don't know if it contributed to his malaise either. THANK YOU CHEWY FOR HAVING THIS ITEM and getting it to us quickly during the pandemic and during Christmas rush. I honestly think we would have lost him if I had not figured out how to increase his health and you delivering it to us with the swiftness you did. Fingers crossed and prayers welcomed, we can get his weight back up a pound or so.
