They Used to be GREAT
My FHV-positive cat used to devour these like crazy. The last batch I got smelled different and she would not eat them at all. I thought I may have gotten a bad batch so I ordered another one. Same smell, same results. I noticed other cat owners saying the same thing.

Unfortunately doesn’t work for my cat!
Unfortunately, my cat won’t touch it. He carefully picks it out even when I cut it up in bite size bits and add to the dry food he loves.

Repeat buyer! Tomlyn makes the Best products~
When Ralphie was rescued, he tested positive for FIV. He definitely needs L-Lysine to boost his immune system and keep him healthy~ Tomlyn products are the Best ones (I tried others). And he Loves them!! I don't need to 'trick' him with pill pockets ;)

Too hard
None of my cats would touch them. Between the smell and the texture, it was a no go.

Cats Enjoy the Taste and Good for Their Health
Our two cats have been using L-Lysine chews for about a year. One cat has a bad eye and both are over 6 years old. They love them and look forward to their "treats" morning and night. I order 4 bags at a time. I have noticed the product has gotten "firmer" since we started using them so we have to use a knife to cut them in pieces. Otherwise, it is a good product and we have noticed a positive difference in their health.
