                GS-441524 Really does work!

                I tried three different kinds of treatment for FIP and this was the best.

                So Grateful - Keksy, the cat, sends big purrs and hugs

                I am so grateful I found PetScrip Pharmacy. My cat was diagnosed with FIP, and when my original overnight medication order for GS-441524 from another pharmacy was lost by UPS over the weekend, I was devastated because he urgently needed his medication and was getting weaker very quickly.

                I did not want to reorder from the same pharmacy, so I started searching online and found PetScrip Pharmacy. What a relief it was to call and reach a live person directly, without going through an automated system. That alone was such a huge plus during a very stressful situation.

                Jessica was incredibly kind, compassionate, and helpful! She truly listened, understood the urgency, and went above and beyond to help get my cat’s medication ready and shipped overnight. On top of that, the price was almost $100 less than the other pharmacy, which was such a blessing.

                A week later, my cat is doing much, much better, and I am beyond thankful! Sending a big purr and hugs to everyone at PetScrip Pharmacy. I highly recommend them and would absolutely use them again.
                Marina.
