    Cats like it; but needs improvement

    By Sms613 on Feb 18, 2021

    My cats have used the same product in capsule form - that is no longer carried by chewy. I changed to this same product in liquid form and the cats like it. I however don’t care for the cap on the bottle. The cap leaks when you pour the dose, and the product is oily and gets all over the place. The company needs to improve the bottle cap.

    2 cats out of 3

    By Mossy on Oct 10, 2020

    I've been able to get two of our three cats to eat their food with the Omega-3 mixed in and have definitely noticed a difference in their coats. The only downside to the product is with the bottle itself (thus the 4 star rating) as the oil tends to slightly drip down the side after dispensing so I keep a paper towel on the shelf to catch it. With this next bottle I think I will transfer the supplement to another dispenser/bottle that works better.

    Amazing Products

    By EWmD on Nov 11, 2020

    Nutramax both Feline and Canine are amazing products. We saw a difference in a week. My cat is a rescue and along with being FIV positive, has some battle damage to his back legs. He's jumping better and his hair is softer after only a few doses.

    going well so far

    By Denise on Sep 21, 2020

    My cat is on Welactin on my vet's advice to support his kidney health. I mix it into a small amount of wet food and so far he's accepting it just fine. I don't know if it's helping his kidneys but he's always had dandruff which has cleared up after about a week of Welactin. I'm introducing it gradually so I don't upset his stomach so he's not on a full dose yet, but so far so good.

    Many benefits

    By ChibsMom on Jul 2, 2020

    My vet recommended Welactin for kidney support for my cat (in addition to special food). It has had the added benefit of improving the health of my cat's skin and coat-we live in a very dry climate and the change has been remarkable-silky, fluffy fur. Plus, he loves the taste so he is eating the special diet. Before adding Welactin he turned his nose up at it. Great product!

    If they like it, they need it.

    By HighDesert on Jul 23, 2020

    This review will sound like a Ravenclaw riddle: If they like it, they need it. If they don't need it, they don't like it. Of 14+ feral cats, the youngest one looked scruffy. Dull, thin, rumpled fur. I offered him this Welactin Omega-3 supplement, He loved it. I fed the Welactin to him every day for 2 or 3 months. After his coat became smooth and shiny like the other cats, he no longer wanted the Welactin. I have offered the Welactin to other cats, but they have healthy, shiny fur and turned up their noses
