Best Cat Multivitamins of 2025

"I was hesitant to try these because my cat is super picky, but she suffers from dry skin in winter. Initially, she gagged when I opened the bag, but after a few days, she was trying to chew through it! Now, she goes wild for them and her fur has transformed from dull to silky smooth. I’ve also noticed an energy boost after she takes them!"

"I’ve been giving these to my dog Louie every morning, and he loves them! They're easy to give and I can tell his coat is softer and shinier. I even make his food myself, so it’s comforting to know he’s getting all the necessary vitamins. The price is great, especially with the subscription!"

"My cat is very ill and extremely picky with food, always begging for treats. I wanted something healthy that wouldn't make her worse. The moment I pulled these out, she came running and absolutely loved them. Definitely worth it!"

"I decided to try Vetriscience Nu Senior Multivitamin after seeing positive reviews. Within weeks, my cat's energy levels improved significantly. They're now more playful and engaged, zooming around the house. Their coat looks fantastic—shinier and softer. These chewable vitamins are a breeze to give, and I truly believe they're making a difference in my cat's health."

"After realizing my cat might have fur mites, I switched to PetArmor Plus, which worked wonders. I want to clarify—the vitamins might not have been the cause of his issues. Now, however, my cat is no longer keen on the taste of these vitamins, making it harder to give them to him. I'm still hoping to find a way to get him to eat them again."

"I cook for my cat, combining meat and broccoli with quality kibble. She's been taking these vitamins for almost a month now and always eats them first, as if they are treats. Anecdotally, she seems more energetic and playful lately."

"I have two finicky cats and they both love the taste of these vitamins. They're nice and soft too. This is my second order, and I will definitely buy them again."

"After finding that my cat's usual vitamins were no longer appealing, I did my research and decided on these. I'm so glad I did! They’re soft, have no bad smell, and my cat eats them with enthusiasm."

"I purchased this because my 17-year-old cat started sneezing a lot. I wanted to give her some additional supplements. Although I think it smells like raw sewage, my cat devours them like there's no tomorrow!"

"My cat, Daisy, had a long-standing issue with gobbling her dry food and throwing up. After starting this supplement mixed with her wet treat, I was worried she might reject it since she's picky. Surprisingly, she seems to enjoy it even more now! Her health is improving, and she has stopped throwing up. Life Extension truly lives up to its name, and I highly recommend it!"

"I have a very picky cat who struggles with finding suitable wet food. I tried this vitamin powder, hoping it would mix well with her meals. To my relief, she eats her food without any hesitation! However, I was disappointed by the amount of powder in the container; it feels almost empty. I also wish I had known it needed refrigeration beforehand, as meal times can get hectic with my other pets."

"After noticing my senior cat developing pica and munching on his litter, I decided to give this product a shot, believing it could address a vitamin deficiency. I’m pleased to say that after 10 days, he has nearly stopped this behavior! Both of my cats don’t even notice it mixed into their canned food, and I’ll definitely continue using it."

"My kitty loves this treat and it's good for her kidneys."

"I put it on my finger and my cat greedily licks it off. I know she's getting her vitamins!"

"This new version does not smell the same and my cat refuses to eat it. If they could bring back the original, that would be amazing!"

"I really appreciate the vitamin content of this product. The fishy flavor has attracted both of my cats, and I've noticed that my 11-year-old Ragdoll has stopped having gunk coming out of her eyes. I'm extremely satisfied!"

"I have to admit, this product has a terrible smell that I wasn't prepared for. Still, my cat seems to enjoy it, and I've seen a noticeable reduction in eye discharge and a softer coat after about a month of use. However, the rank odor is something to consider."

"While I know that lysine supplements are effective, I had to stop using this one after just a few days due to an overwhelming smell that reminded me of cat food mixed with seaweed. It was just too much for me and my cat."

"I think this is a really good multivitamin. The ingredients look good. Both of my cats think it's a treat and can't wait to get one daily. It doesn't upset my IBS kitty's stomach either. Good stuff."

"I bought these vitamins for my son's cat who had NO appetite and looked down. Within a week of using it, everything changed. The kitten eats more and looks very alert. I am very satisfied with the product and will continue to buy it."

"My cat won't touch these vitamins. She will sniff them and quickly turn away. If I try to put it in her food, she'll refuse to eat her food as well."

"My dog was on the brink of death, and after starting her on this liquid vitamin, she has completely turned around. She's regained her appetite and her coat's color has returned. I was thrilled to find a plant-based vitamin for her since she's picky and won't eat chews. The dropper format is super easy to use, and I love that it's in a glass container to avoid plastic leaching."

"I've used this product before but got it this time to help my '911' rescue kitten. Almost immediately, she started to come back to life. I found the best way to give it to her is by adding drops into a 'squeshie' cat treat. Thank you for your commitment to honest products; I usually don't write reviews!"

"I have a very fussy cat, and after trying various supplements, my vet recommended an expensive option. I decided to try this one instead, which was much cheaper and had almost the same ingredients. Surprisingly, my cat likes the flavor! In just a week, I've noticed her fur looks better, her personality has returned, and she’s acting like a kitten again. Huge changes!"

"I've been using this product for 35 years! Every dog, cat, and horse should use it. It's packed with goodness, and my dogs love the taste. I give it for life to keep them active and smart. One bottle lasts my 41-pound dog over three months, making it very affordable!"

"When I started adding this to my dog's food, I noticed a significant improvement. His skin and coat have become healthier, and his stools are better too. This supplement is a fantastic addition to his bland diet due to health issues."

"After using this product for just a week, my dog's hair started growing back. She had been completely bald in some areas for months, but now she has a nice layer of hair on her tummy and neck. I'm amazed at the results!"
