I've ordered numerous refills for my Litter Champs since I began using the Litter Champs. Each time the refill liners were the same...an off-white color with a pleasant smell. Great news...I just opened a new box of liners yesterday and was surprised when I saw that the box contained blue/green colored liners. I thought they had sent the wrong item, but enclosed inside the box was a notice to the customer stating that these liners are "made with the same durability, construction, and odor control as before but they are now Biodegradable!" This makes the Litter Champ even better! I'm very environmentally conscious. I use biodegradable litter and biodegradable poop bags, so these new liners are just another way of being eco-friendly!

Pros: Refill liners are now biodegradable!

Cons: Hard to find in stores

What a great idea, Hope you have good luck finding them.

Pros: Good product

Cons: Hard to find
