I possess 5 cats and have acquired amazing and unbelievable experience. Five years ago one of my cats was diagnosed with leucosis...I was devastated and shattered hitting rock bottom when the vet told me it was a deadly disease and the only relief she could get was to put her down...No way I could accept this!!! Previous to that I had had very good results with some DXN products. My liver values were quite bad and high but after taking these products for 5 months and no meds at all they went back to normal! I decided to give it a go. I started giving her big doses on regular bases twice a day. After a few days she started eating alone (I was feeding her with a before) and her behaviour changed completely. Four months later I took her to the same vet and she asked me if this was another cat. She did some blood tests and came back speechless and flabbergasted. She said there was no trace whatsoever of the deadly disease! My cat is now 12 years old, agile and in the best of health. Three years ago another cat of mine was diagnosed with grave jaundice (Gelbsucht) and I heard the same story from another vet - deadly disease and the only "help" was to put her down. I didn't take it seriously this time and started treating her with the same products. When the vet saw her after some time he couldn't believe his eyes and said that never in a million years had he thought that my cat would survive. There was no sign of the deadly disease at all! A big thank you to DXN!!! If anyone doubts this story I can provide the written affirmation from one of the vets and my before, after liver values too.
