Why should an allegedly 'natural' chemical be any better long term than Piriton? And is there any actual good evidence that quercetin helps allergies? I mean from a peer reviewed source, not some online peddler of 'woo'.

What have you done to try to find what your cat is actually allergic to?

 

I'm a little taken aback by your confrontational response. Just so you know, I have spent more than £4000 having my cat tested over the past 2 months and the Quercetin is to control symptoms while he is on an elimination diet. As anyone who has a pet with allergies knows, it takes time to determine the allergen. And sometimes you still don't really know.

There is a considerable amount of evidence to show that Quercetin helps the inflammatory response in both humans and animals. I'm surprised that you are advocating for Piriton. It doesn't work for every animal/human. It can only be used for a short duration and even then loses efficacy over time. I would encourage you to do some research yourself before leaving such ignorant responses to questions you have no answers for.

 

Dosing doesn’t seem complicated, weight of cat determines the correct mg, a specific cat pill isn’t needed and any tummy upset clears quickly.
However I was reading it should only be given for up to 12 weeks at a time so may not be suitable for your long term situation.

Perhaps the problem is behavioural if tests and diet haven’t changed anything.
