Review on Vetoquinol Enisyl-F Oral Paste: Tasty Tuna L-Lysine Supplement for Cats - 3.4oz (100mL) Pump for Optimum Feline Health by Nicole Brand

My cats, now 15 and 17 years old, were rescued by kittens from a feral colony. All have a respiratory virus of varying degrees of severity that worries them more and more as they get older. Enisyl-F Paste with fish flavor supports your immune system and is well tolerated. I use a popsicle stick to spread it on my paw and leg and they lick it off. After many failures, using a popsicle stick (or tongue detonator) works best for me and my cats, but some cats take it differently. The container lasts a long time.
