Had the BillaFlow Pro about 4 months now and we're absolutely loving it. My kitty Margaret is finally drinking water consistently, and her vet noticed a massive improvement at her last check-up compared to before. 10/10 purchase!

Had high expectations for this thing and it exceeded my expecations! My old boy Baxter used to barely touch his bowl and now I catch him drinking from the BillaFlow Pro all day. Even his coat looks better. Wish I'd bought one years ago!

Two cats, one fussy drinker, and the BillaFlow Pro won them both over in about a week. So quiet I forget it's running. My only regret is not getting it sooner. 10/10.

Been using the BillaFlow Pro for a couple of months now and the difference in Poppy is night and day. She's more playful, drinking heaps more, and her last vet visit came back great. Highly recommend to any cat parent!
