    The cats liked the taste and they got better much faster. I run a cat shelter and I will buy this product again. The only thing bad is there is no way to measure it to dose it as directed. But this product is not dangerous if you give them more than directed.


    Treats vs. Paste Treats get 5 Stars Paste get 2 1/2 Stars

    I tried the paste first and it went very fast it was difficult to properly measure and I felt like I was forcing my cat to take the paste since he clearly did not like the taste on his own.

    Next I tried the treats and he will eat those on his own. I just wish the treats were either firmer or smaller. My cat has an overbite so it is difficult for him to eat them with out a little help :) But treats are definitely the way to go!

    I am happy to report that my cat who needs Lysine for her immune system loves this product and I have no problem getting her to eat them.
