Oh Lacey....I'm sorry to hear of the litter smell but I think it "MIGHT" be the brand of litter you are using.
I pray a petsmart is near you. It is the cheapest place for supplies and through my experience some of the most advertised litters don't work well. I use - the brand called ExquisiCat® Scoop Litter.
The link below is just one of the types available. I have one cat but have used multiple cat and non multiple cat letter versions. BUT I USE unscented. The link below is just and example of the box. In the store the cost is 12.00 for 40 lbs and 9.99 for 25 lbs.
It is scoopable litter so when socks (my cat) uses the litter it clumps like a ball. Also their is no scent.
I have used other brands and this one works the best for me. I don't think you will need a mask. Also, I tend to wait and not do the litter right after cat uses the litter.
Also food is cheaper at petco/pet smart stores.
Remember, for your dry food, and since you only have one cat. I put my cat food in a Tupperware type cereal container - like this....it does NOT have to be Tupperware - any Rubbermaid - walmart/target/CVS food container that keeps food airtight. THis will ensure that the cats food stays fresh. I bought a container large enough for the small bag. I don't buy the super large bags of dry food because it takes too long for one cat to finish. SO the only food I buy at petsmart is the can food - I used to buy fancy feast kitten. Which cats LOVE. Fancy feast is like CRACK to cats. So I only give my cat fancy feast on SUNDAYS as a treat.
