Hello, I looked over the question you sent. 
This is not a case that requires a visit to a vet clinic or the ER. However, you need to keep a close eye on it.
Cats' poops usually smell worse than dogs. (That's by nature. The difference in the processing power of the digestive system.) This makes it hard for many cat owners.
Changing the litter box's sand often or spraying deodorant to remove odors on the litter box is one of the ways.
Or an expensive litter box that automatically changes sand mechanically is recommended.
Please do not hesitate to ask any further questions you may have. Thank you.

I have tried so many different litters and food but I don’t know if food helps contribute to Oder when they are using the restroom. Do you have any recommended litter and litter boxes to help eliminate Oder and a recommended food

what kind of litter and litter box would you Recommend for odor
