    Nothing short of a miracle!

    It took going to a second vet for a second opinion to know our girl kitten at 6 months having FIP. The first vet wanted to run a series of tests before saying anything. The second vet took one look at her and knew her diagnosis. A bleak diagnosis that this 6 months old that had turned into skin and bone with a huge extended tummy would not last long. When she called other vets for potential treatment, was told of one that would cost us around $10k AUD. Impossible for most of us. 3 hours later at home I came upon this website and thought it was a scam, but we had nothing to lose and with hope I ordered a small quantity to make sure it arrived. It arrived within days! I ordered it on 2nd Jul after 10pm and they arrived before lunch on 8th July! By the weekend we saw changes and literally an improvement every day. From her stomach shrinking, to not having to lie down in one position all day (she could hardly move), she couldn’t clean herself, she started eating (I hand fed her for a few weeks of treatment). We are now 5 weeks in and she is the cheekiest, liveliest and happiest cat I’ve seen! Even her brother from same litter can’t keep up with her! Thank you so much for this treatment! I’ve since taking her to the second vet and her entire team were amazed that they took pictures of her and were crying with joy! If I could give this more than 5 stars I would!!! It’s given a little girl her life back, a little boy kitten his sister back and my family a beautiful cherished pet.Read more

    Very impressed with this product

    My ginger & white Maine Coon cat, Dusty, had Wet FIP. So no appetite, a bloated stomach, and no energy. Within a week, his bloated stomach had disappeared, and after 10 days his energy had increased to the extent that he was climbing trees again and playing with his younger sister, a kitten. His appetite increased with the B12 injection, but reduced without it. I would definitely have continued to use the B12 addition that I used in the first week of his treatment had I known the benefits of it, as his appetite has since waned. I am overall pleased with the rapid response to the treatment over 2 weeks into his recovery. My recommendation would be to use a 25 guage needle, 16mm in length. The 23g and less is too hard to use. Overall, my cat has been receptive to the injections. I am so pleased with the results and I would recommend everyone to use these treatments - it's well worth the expense to see your beloved pet well again.Read more

    A miracle cure

    We are on day 31 of the treatment for Skye, our Ragdoll. No treatments are available in my country and we were told to euthanise her. Thank goodness for Cure FIP. We used the injectables for 2 weeks and now the capsules. Skye did initially crash and required hospitalised treatment including a blood transfusion and oxygen but we managed to keep her going so the medicine had time to work. Now she is bouncing back and has all the vets at her clinic talking about her. I have even been asked as to where to get this treatment for another FIP cat. She is our little miracle cat and we were so glad that she made it to her 1st birthday. I will be stocking up on more medicine to complete her treatment.Read more
