Had hopes that these treats could replace another L-Lysine treat that was loved but the formula changed or ingredients shifted or something and kitty stopped liking them cold. Anyway, these Felisyl treats smell and look exactly like the new/old treats, so no help at all. My discriminating kitty won't eat them. The Felisyl seem exactly like the other "updated" brand, same manufacturer, different brand I guess? One of my cats will eat these, but they just smell weird to me and I hesitate to give them to him. I always had to break the treats up into a few pieces, too big for my kitties.
The product universally liked by my cats, made by 21st century/essential pet appears to have been discontinued. I decided to try these instead. They are not soft and chewy. My cats are eating them, but I am not too sure how well they work.
I bought this for one of my cats at the recommendation of my vet. They are not chewy at all - they are very hard. I have 5 cats and offered them each a treat. No one will eat them. I tried breaking one up and putting it in their other dry food, and they eat around it. Terrible.
I was worried that my cats wouldn't like the flavor of these. On the contrary-I have to hide the bag! They're all over me as soon as they see it, and it's definitely made a difference because they're not sneezy within 24 hours of eating one!
