If you’re looking for a 7kg daily-use pack: Original
Mr. LEE Original is a 7kg line to check out if your household is looking for everyday clumping litter. The official detail page introduces the product focusing on absorption and clumping. If you’re reordering a product you’ve used before, make sure not only the package photo but also the name ‘Original’ and the scent match. Even within the same brand, different lines can be ordered.[1]
If you want to compare scent options together: Odor Killer
In Odor Killer, you can check detailed names like 7kg Unscented and Amazing. If you want unscented, go for Unscented; if you’re looking for a herbal scent, Amazing is a good comparison. Since the official page introduces several editions, make sure to read through the current options at the store.[2]
If you want an unscented 9kg pack: Classic
Odor Killer Classic comes in a 9kg unscented pack. It’s a good comparison for cat owners who want to match the number of times a bag is opened or keep refill stock at 9kg. Be careful when ordering, as the 7kg Odor Killer with “Classic” in the name is a same-weight product, and the quantity calculation differs.[3]
Four boxes are enough for a repurchase note
- Product name: Mr.LEE + specific line
- Option: Unscented or exact scent name
- Weight per bag and number of bags ordered
- Opening date and what to check for the next purchase
Purina recommends a gradual transition when switching to new litter.[4] Keeping a record of the line that works well at home makes it easier to decide what to keep and what to change if you have to choose another option due to a sold-out stock. The advantage of the Mr.LEE lineup is that you can specify the choice by weight and scent.
If you want unscented, which should you choose: 7kg or 9kg?
Odor Killer Unscented comes in 7kg, and Odor Killer Classic in 9kg unscented. You can compare according to how you split up a bag or your usual refill amount. The difference is that even within the unscented option, you can choose the packaging weight.
