Best supplement
I have given my rescue cats Feline 40 for several years. My last cats lived long and happy lives supported by it. After losing my last cat I rescued two more. Both have FIV, are 5 and 8 and for the moment have no symptoms. I gave them Feline 40 as soon as they came home, to help boost their immune systems. That was 7 months ago and so far they have great appetites, eating raw food and they really have settled in well. Their coats have improved and itching has subsided so much. I can highly recommend Feline 40 there is nothing as good.

Brilliant results
We have had our rescue cat Jazzy since April 2022. She had an eye removal operation last August. She's always had very irritable skin and was nervy. She's been on Feline 40 for coming up to 6 months or so and we've seen a massive improvement. Her fur is beautiful. She has very little, if any, itchy skin problems and she's seeming more relaxed despite having to get used to her new vision. I am delighted. No more nasty steroid jabs!

great for hyper sensitive skin
My young small cat really struggled with skin allergy and over-grooming - his brother and our other cat had no such issues. I tried all sorts of different foods and treatments but still he was in such a state and had groomed his back legs bald. He looked awful. A couple of months on feline 40 and he was back to normal and his fur was so soft and healthy - especially on his back legs. That was over a year ago and he is a very happy cat with half a scoop of feline 40 daily. Feline 40 is expensive but SO worth it!

Helped 17 year old cat
My Ragdoll was very thin, not hungry, wobbly on his feet, fur was lacklustre and I was fearing that he was literally on his last legs. I saw Feline40 and thought lets give it a go, other reviews were good and it was the last resort. I started with half a measure with his food in the morning and half at night. Well, I really wouldn't have believed it, a few days later I thought I saw him in the garden but the image disappeared. I went to look and couldn't believe that he had climbed some steps and was staring at a bush hunting. His appetite improved greatly, he got stronger, he was keen to go outside and even going through the undergrowth. He has come back to life and I am so pleased I tried this, it is well worth the money. I was so thrilled I told my friend about CaninePrime as she has an old dog and he was showing his age. She gave it a go and now he is trotting around the park and chasing other dogs. He wants to play now and brings out his toys. Give it a try.

Excellent supplement
I tried this product on my 3 rescue cats, their coats are so incredibly shiny now, they are so fit, healthy, and full of fun and love. Even my vet commented on how well they looked, I showed her Feline40 she agreed it's an excellent product. So I highly recommend it and have done to everyone I know who has cats. Now about to buy the dog supplement. Thank you so much for caring about our loved ones.
