I used to have a couple of cats, and nothing works regarding absorbing odors. For our uses, any brand of cat litter, peat moss, saw dust, etc. will be equally ineffective for absorbing odors, but about equal for absorbing moisture. I prefer peat moss and saw dust because it's lighter than litter.
Back in the 70s I was in a Sears store in Minot, ND, when the announcement came over the intercom, "Ted Williams to the sporting goods department, please. Ted Williams to sporting goods." I was with a salesman; Sears's baseball stuff was endorsed by Ted Williams, but I was surprised he'd be in Minot, so I asked if he was really there. "No," the guy said, "we've got a new girl on the intercom." Immediately she said, "Pete Moss to the garden supply department, please. Pete Moss to garden supplies."
(This was back when men were men and women were girls; please excuse the salesperson and me for quoting him.)
