Review: Healthier cats with Under the Weather products - I care for TNR cats. They sometimes get under the weather. So this product is perfect. I just mix in the wet food as directed. After just 2 days they noticeably felt better. Very easy to use. They didn’t notice any oder or taste. So they just ate it willingly. The sides effects are good ones. Healthier looking eyes and less sneezing. I’d say it’s an excellent value.
Review: Picky kitty likes it - go slow - This has been really helpful. We mix it in with wet food. Started just a tiny bit at a time and add water mix it in. Once he got used to that we started adding more. Now he finds it palatable and he’s super picky. Every now and then if I add too much he’ll let me know haha, but it’s helped him put on weight. He looks chunky in the pic but it’s all fluff he weighs like 8lb. Vet said he needs to gain weight and can’t lose anymore.
