Saved my cat

I've had my cat, Rachel, for over 10 years and several times a year she would develop upper respiratory illnesses. I'd take her to the vet and they'd run all sorts

I've had my cat, Rachel, for over 10 years and several times a year she would develop upper respiratory illnesses. I'd take her to the vet and they'd run all sorts of tests but there was no diagnosis each time. She'd get antibiotics that would temporarily get rid of it but after a few weeks it would be back. Sometimes it would be worse than others and in October she developed one of the worst and I was seriously considered euthanizing her as I couldn't afford vet visit, test, and medicine again> I got a flier about Chewy having a pharmacy but couldn't afford even a vet visit and meds so decided to try their homeopathic medicine and ordered both the nose drops and a lysine powder (both had a money back guarantee so I was willing to try anything). I started both on the day it arrived and within 2 days I was noticing the congestion was less as well as the yucky green nasal discharge. It's now 2 weeks later and she's barely wheezing and the nasal discharge is there but reduced in amount and clear. When I get my next check in a few days I'm going to stock up on both so as soon as I see any signs I can start immediately and hopefully she won't get to the stage she was at when I started her on this magic medicine!

Works well for our cat

Vet recommended daily lysine for our cat. This one works well, she has not had issues with her eyes while she is taking it and the dosage of one scoop daily is convenient

Within a week of switching to this from Viralys, my cat’s eye was mucusy.

Didn’t work for us. Will be sticking with Viralys.

Despite other reviews my cat immediately detected the powder mixed in his food and he refused to eat it.

She likes it

I’ve definitely noticed a difference, she’s got more energy, plays a lot more, and her fur’s way softer. I also love that it doesn’t smell bad and she actually eats

She likes it!

What a relief, my finicky eater likes it! I mix half a tsp with one squeezeups and she licks plate clean! Vet diagnose her with feline herpes and prescribed Vetoquinol

What a relief, my finicky eater likes it! I mix half a tsp with one squeezeups and she licks plate clean! Vet diagnose her with feline herpes and prescribed Vetoquinol gel but it was a struggle for her to take it. She stopped eating her food if I tried to mix it in. It's winter and she has another flare up. I decided to try the powder out of desperation, I got tired of losing her trust. I wanted something to work that she liked. She likes it and symptoms are subsiding. Hopefully it will save me a trip to the vet.

Day three starting to give my girl lysine supplement. She used to take lysine every day last year and she seemed to be okay, and I wanted to put her back on the supplement to help her immune issues and when allergies become a problem. She eats it I mix it with her wet food, seems to be working. I used to give her treat form but decided to try powder!
