I own two parakeets, SpongeBob and Patrick. Despite their small size, they produce an alarmingy amount of waste, so I never bothered with cage liners and used paper towels instead. I came across these liners on Amazon and purchased them on a whim. I’m so happy that I did! They’re super absorbent, so I spend half the amount of time cleaning out their cage. Even though they do absorb more waste, it actually smells less! The liner fits perfectly, so I have no complaints. I will definitely be repurchasing!
