They actually liked it. They ate it, however after a while they vomit, unlike the other brand I have given them.

Really improved my cat's life
I almost never write product reviews, especially on Amazon. So this is a testament to how well this stuff works. I have an exotic shorthair. Flat face, goopey eyes even on the best of days, trouble breathing, etc. My cat also seems to have almost no sense of smell probably because she has tiny nostrils and respiratory issues - this means she eats only one type of particularly pungent kibble, no interest in any of the 20+ different treat brands I've got her, no interest in wet food, no interest in any human food. I do not agree with the breed, she was a rescue and really is the sweetest cat ever. Her life has been difficult because of her breed specific issues. I've had her on this for around 2 weeks and the difference is astounding. I haven't had to wipe her face at all this week, very little goops (nothing she can't groom off herself), her breathing is way better, and she is taking an interest in other food and sniffing EVERYTHING. I'm shocked. I assumed this would help a bit but she really seems so much more lively and happy. She's acting like an actual cat, playing and running around (which would have tired her out way quicker before), doing cat things she hasn't done before. I've had her for 2 years and I've never seen her like this. YMMV of course, and I can't tell if the results will last long term. But I am very satisfied with this purchase. Also great value. No scoop is included but it's only a 1/8 tsp twice a week sprinkled over her food. This will last easily a year+. She hasn't turned her nose up at it yet so I don't think she notices it's there. Definitely worth a try. Especially if you have a brachycephalic cat breed (flat face).

Has vastly improved my housecat's drippy nose and sneezing
Having spent 2K on seeing 5 vets over four months, this appears to have massively reduced my cat's drippy nose and sneezing and she can now obviously smell more, and as a result, is less of a fussy eater. The vets reached the point where they could offer no more help, other than perhaps a referral for a CT scan, etc. but as my cat was basically otherwise well, and she chooses to remain indoors, this felt unnecessary. We did agree to an anaesthetic and nasal camera, which reassured us that polyps/growths appear unlikely, so before going down that route, I would thoroughly recommend giving this a try. Within 5 days of just a teeny amount in her food, once a day, there was a massive improvement.

Ok!
Usato per gattini che già dopo un mese di vita hanno preso l'herpesvirus dalla mamma..con fatica e dopo mesi posso ritenermi soddisfatta è stato comunque un supporto in più per il loro sistema immunitario!
