  • Natural cat litter (both clumping & non-clumping): 25 pounds per week or 100 pounds per month

Well, cat litter consumption isn’t an exact science. Let’s say you have one small cat with a standard litter box (18’’x24’’), so how much cat litter per week or how many pounds of litter per box to use?

On average, you will go through about 7 pounds of cat litter each week, in other words, 28 pounds per month. But if you have a large cat breed, it will need at least 10 pounds per week or around 40 pounds per month.

In fact, the actual amount required varies depending on the particular type of cat litter you are using, how frequently you change the litter box, and other important factors like your cat’s health condition.

If your little buddy is suffering from a medical condition like kidney disease, she will urinate more often. So, the requirement for cat litter goes as high as 10 to 15 pounds per week, which equals 40 to 60 pounds per month.

Non-clumping cat litter

Non Clumping Cat Litter

Although non-clumping cat litter is generally cheaper than clumping one, you may use more bags of non-clumping cat litter per week than usual, which will ultimately increase the cost.

cat litter smells like ammonia

Urine – including cat urine – contains a substance called urea. It doesn’t smell much but if you let it sit for a while, bacteria will start to break down the urea into ammonia, which releases the ammonia odor.

Typically, you won’t notice this smell because the litter will cover it. However, in some cases, the smell can be more pungent than usual. The stinky odor can occur when your cat is dehydrated or in case she has an inadequate diet. Also, it can be indicative of health concerns including infections and illness.

Whatever reason it may be, it’s important to take steps to minimize the smell and the harm or disruption it causes. To keep the ammonia smell at bay, try to clean the litter box as regularly as possible and ensure that your cat has plenty to drink.
