Kicked the virus!
By Dorie on Oct 5, 2020
One of our 4 cats had herpes/calici virus symptoms all summer long. The other 3 cats were battling the virus on their own without medication; however it hit 11 year old Merry very hard. 2 courses of antibiotics cleared the bacterial infection but the virus symptoms remained. Thankfully Famciclovir improved and then relieved him of all symptoms. We are almost finished with a 2 week course and he is symptom free and returning to normal. This is a God-send for him!

By Ziva on Apr 2, 2020
I nearly fell over when the pharmacy told me they wanted $ 148.00 for this prescription for my cat. Checked online and found it on sale at Chewy for about $12.00 ! Was very simple to get the vets prescription to them and it was delivered quickly. I thank you and my cat thanks you too !

Seems to work well
By Catmom on Oct 21, 2019
My cat has feline Herpes with recurrent sinus infections. Usually an antibiotic helps, but he was on 2 different antibiotics and no improvement so the Vet prescribed this and it is helping. I just wish that I could have emailed the script instead of sending it by mail, priority mail because I needed it fast.

Feline Herper
By Tauntaun on Aug 21, 2019
Very effective for a very persistent illness. Chewy delivered it fast. If you have a problem giving pills to your cat...try a Pill Popper, like a syringe, but you put the pill in it. I only see one on Chewy, I got mine from another retail giant...more options there. With very little struggle, I was able to give my cat all the pills, that would have be impossible without the tool.
