A total blessing
My 14-year-old Bengal,s poo became sloppy and smelt offensive, he also scratched so much despite being a house cat and free of parasites. I read about Feline 40 and with the money-back guarantee I thought I'd try it before resorting to steroids and other drugs. I'm so happy! Both problems resolved within a week, totally! His poo is 'proper' again, formed and just the normal cat-poo smell. He hasn't scratched in ages. There are no doubt other benefits going on inside him, but these are the most obvious ones. I will never stop buying this product while I have my wonderful, intelligent, quirky friend with me.

Matted hair
I have a ragdoll cat, who needs regular grooming to try to avoid Matt's forming, although I groomed her everyday, de got Matt's in her hair on a daily basis, and twice had to be sedated to have them removed. Since using Feline 40, there have been no more Matt's forming, and she has healthy shiny fur. A big thank you to the the vet who designed this amazing formula, and one added bonus, she is as frisky as a kitten, at 10 hears old

Feline 40
Our 11 year old visually impaired cat shows a marked perkiness after one month on F40. Has always had a silky coat but even that looks a bit glossier. She invites play, seems livelier and is generally more engaged with her life. Would recommend.

Honestly don't know if its doing anything....
I've just finished the 3 pot, as I bought 3 to get a cheaper price. I have a 14 year old female in relatively good health apart from recurring cystitis issues she's on medication for and an approx 3 year old rescue male. I honestly haven't noticed any changes in their overall health. They both seem to like it, even my girl who is very fussy. I'm going to keep on with it, as I want to do everything I possibly can to keep them both at optimum health.
