Some years back, a person did an exhaustive test of the commercial litters (concerning some bad side-effects, thus: which is actually superior, least harmful.)

Fresh Choice is what I've used since. Via usual bizness acquisitions, it's now called "[Pro Pet] Fresh Results" Dunno sales regions; apparently HQ is at Cincinnati OH, at (800) 645-5154. FWIW
Made from corn cobs, only faintly 'nice smelling', clumps well; they say, "Our patented Triple-action On Demand odor control is the most advanced system with high absorbency effective odor control and long-lasting fragrance."

Ad-speak aside, it appears to deliver on that. It ain't the cheapest (as Ruskin says, about that) but because it lasts a while, it may still be most economical.. Dunno where mine pee when outside, but I've smelled nada, all along.

'Course if ya gots a one like Fat Freddie's, pissing in boots? ..so far I'm lucky. A neighbor did find a solution to that, though: Folex™ (no rinse) carpet spot remover. $-back guarantee (800) 253-6102 (One (ill) cat did pee once.. fortunately I saw it/when fresh, no odor.) Stuff worked, as none developed.

Guess you didn't have this problem, then...

Earlier, some foofarah about clay-based litters seems to have been resolved as: mainly involving early kittenhood and per ASPCA, Any cat older than that detected eating litter should be taken to a veterinarian, since this behavior often indicates anemia or other dietary deficiencies.

MrroWWWrrr. Dunno the smells you were describing (formerly) whether from odors on shedded fur (?) or some other source. Obviously cats are innately self-grooming (unless ill, mentally or physically). At least the dozen plus I've lived with over the years, even when sniffed through their fur ... have fit that reputation of clean-smelling. And when one is sleeping on your arm, your nose Knows. Even the in/out pair, when picked up and sniffed around neck fur, sometimes seem to have had a slightly-perfumed aroma!--which I cannot explain--but there you are.

(My sniffer is broken or ..maybe needs to sniff 100 more, so I can employ Stats? the 21st Century's substitute for experience.) ;^> There's so too-Much "info" out there now--many suggestions eloquently presented/but bogus--that I conclude that, especially on a diet of only dry food, (all now employing pheromone research to formulate a spray-on attractant that's very effective) ... it's impossible to separate the marketing-BS from any truthiness. (Not only re such horrors as Meloxicam and some other vet-nostrums.)

Luck to your kittehs; it's a crap shoot learning how to keep them healthy: they Never tell or show problems: pure survival-in-wild camouflage. We have to look damn close at eyes, *mouth!, fur condition, gait, mood changes ... and most in our manically distracted kultur ever have or take the t i m e , in-time. Meanwhile Vets charge just like meds-in-Murica taught.

* Squamous cell cancer occurs often, IMGuesstimate: because of the huge/profitable expense of anaesthesia at most vets. And fact that so few ever look closely, when we see one yawn.. for the red-gums that foretell mouth problems (kittens can be trained to let one use a 'finger-toothbrush' periodically.) Mine have all been 'old'; lost Sierra to that, at 16. May your mileage Vary.



Ed: add

A pleasure to hear an account that well informed. Have done many a sub-Q, too. A friend's cat really loved the relief it gave her: she would [I saw this..] jump up on table--the chandelier was the IV-stand--and wait impatiently for her treat given at conclusion. But unnecessary.

(When I feel a need to weep.. it's for humanity puppehs n'kittehs, those not nearly so fortunate as to be cared for by informed staff-Persons. They know-not what they Do Do, so often by feeding Friskies and other disguised %high of meat by-products, signified by what comes in the first two or three items in Ingredients list. {sigh}

Curse the Chinese providers of anything meant to be eaten by mammals! (Stay happy/don't read Food Pets Die For.) The Refs alone would trigger any slightest tendency towards Depression.

Rilly nice to hear that the IGM's collective talents include bitchin animal care, too..
