My cats don’t seem to like these. I have to cut them up small and mix them in their wet food.
My cats don’t seem to like these. They don’t smell bad to me, but the cats take one sniff and walk away. Only two of the five cats I’ve tried to feed these to have actually even attempted to eat them. One started to eat one then spit it out, the other cat has ate a few. He’ll eat pretty much anything though. After a week or so he’s stopped eating them as well, he still occasionally starts to chew on one but spits it back out when he realizes what it is. I’ve fed them all chewable supplements before that had a similar look and texture, so it seems to be the smell or taste that they don’t like, not the shape or texture. I’ve tried cutting the pieces a bit smaller and mixing in with their regular treats, but they still eat everything else and leave these. The only way I’ve managed to get any of the other cats to eat these is by cutting them up really small and mixing them in with their regular wet pate cat food. That’s a bit time consuming though since I have to watch each cat to make sure they eat their portion with the supplement in it. The ingredients list looks good, these should be a great for their immune health. I have fed them other supplements with similar ingredients. Those worked well. I would like to feed this to my cats, they just don’t like them. I will probably continue chopping these up and mixing them in their regular food until I run out., but they’re not worth the price for me.

Helpful supplement for my cat’s overall health
This cat supplement seems to support my cat’s immune system well. The soft chews are easy for her to eat and she seems to enjoy the taste. I like that it targets both immune health and gut support in one product. After a few weeks, she appears more energetic and her digestion seems smoother. The size of the chew is convenient for daily use. It does not upset her stomach and is gentle to administer. The ingredients seem thoughtfully chosen and of good quality. I also appreciate that it is easy to store and keeps well. Giving it daily has become part of our routine and she takes it willingly. It feels reassuring to know she is getting extra support for her overall health. The packaging is clear and informative. Overall, this supplement offers a convenient and effective way to help maintain a healthy cat. I would recommend it to cat owners looking for immune and digestive support. Great value for the money!

Cats won’t notice if you sneak these in their kibble.
My cats won’t eat these as treats, but they also do not notice when I add them to their regular kibbles and will scarf them down. Whether they work or not in the long term is hard to say, but the first hurdle is getting them inside the cat, so… I give them a five out of five on eatability and ease of use, and quality. Effectiveness is still being evaluated. My cats are pretty mellow, so whether these have a calming effect or not is hard to say. But I will tell you that giving them these supplements was a calm experience for me and that puts me ahead of the game.

Cats Show Little Interest in These
Checking the ingredient list, this supplement looks to be potentially beneficial for the health of my three cats. However, that really makes no difference if I can’t get them to eat these. All three of them have not really shown much interest. There have been some attempts to eat them, but the result is always a soggy half eaten supplement left on the ground afterwards, so I have to assume they don’t think these taste good. I’ll keep trying but not looking good… not something I will re-order unless one of more of the cats suddenly takes an interest in them. On the positive side, these don’t smell bad.

Neither of My Cats Would Touch It
I have two cats, a pickier indoor cat and an outdoor cat that will eat just about anything. I got this mainly for my indoor cat because she has a sensitive stomach and I thought maybe improving her gut biome would help her. My indoor cat was not at all interested in these. I put one in front of her, she gave a sniff and looked at me as if to say, “Really?”I thought maybe she was being picky, so I went to my outdoor cat, hoping she would prove to be a more willing test subject. She acted interested initially, picked it up in her mouth, dropped it and walked away.Since I have been in Vine I have not yet found a single treat that my outdoor cat would not eat so I am deeply skeptical about the taste of these.The jar arrived well sealed and inside the container, the treats were in excellent condition. They were moist morsels and did not have any strong off/bad odors. From all appearances, it appears to be a quality product, but neither of my cats wanted anything to do with it. Since these are somewhat pricey and nonreturnable, I am not sure it would be worth the gamble.

Cat Health Supplement with Gut Boost Manufactured in the USA
The ninety (90) soft chew container will provide the average cat with a 30-45 day supply. Larger cats may require additional chews. See the container for the recommended number of daily chews based on your cat’s body weight.The active ingredients can potentially provide a number of health benefits to your feline friend(s). There are also inactive secondary ingredients commonly used in these types of pet products. WellJoy is a USA company with its manufacturing facility located in the state of Vermont, though it uses globally sourced ingredients.My cat seems to like the chicken flavored chews, and I have not seen any negative effects. The product is not intended for kittens, which are generally considered cats less than one year of age. But the container recommends that it is not suitable for cats less than six months of age.Among the potential health benefits are the products support of a strong respiratory system, immune system, and improved gut health. The price does seem a little high given the daily number of recommended chews. The long-term effects are unknown unless your cat has a specific stomach problem that these chews might address.
