Small Pet Select does sell pelleted paper litter.  They have 2 varieties.  One is supposedly for cats, although there are reviews on it from several rabbit owners.  The other pelleted paper litter is for small animals.  I don’t know what the difference is between them.  Neither one has baking soda.  The price may be higher than Yesterday’s News, but the litter does get good reviews.  Go to their website and put litter in the search box to see both varieties and the product highlights.

I use Oxbow Eco Straw, but I’ve never noticed a strong smell.  It has very little scent at all to me, but I do remember reading another comment from someone who didn’t like the smell.  I cover the pellets with Carefresh for a softer surface under my bunnies’ feet.

Small Pet Select’s version of the pine pellets are much less fragrant, in my experience, and also if you haven’t tried already, you can try putting down a litter screen to prevent dust/direct exposure to the litter: https://www.reddit.com/r/Rabbits/comments/sh5dzp/housing_example_litterbox_setup/

Yesterdays news was discontinued 😭😭😭 it was so disappointing to me too. I currently am using small pets select paper pellets (the rabbit version) but they’re REALLY crumbly, I don’t know if the cat version is more whole or not. It tracks more that the paper bedding does but it more absorbent and odor locking. I do want to try the eco straw pellets actually, maybe the smell was from the specific seller you got it from? You could try small pets select pine pellets if you want, I think the scent does differ between the brands of pellets. I’m pretty sure it’s depending on how well they were kiln dried? Feline pine REEKS of pine like to the point where even I’m bothered by it, the rabbit rescue I know uses pine pellets (not sure of what brand) but they don’t have a scent at all. I am wondering about aspen pellets, I know Aspen shavings are safer than pine or cedar shavings because they have a lesser content of the oils. I just searched it up and they are a thing, kinda wanna try but I’ve heard nothing about it from other bunny owners. I would probably go with the small select newspaper pellets just to be on the safe side with your buns respiratory tract for now 🙂

would not use baking soda in the litter considering bun already has respiratory issues, I don’t think they really help with the odor that much either.

What about carefresh? I used to use it before I switched to pine pellets and it works well. Maybe not quite as good on odor control but still pretty good and it’s paper based and has no smell.
