Don't know the measurement's of a zoozone but those liner's were £25 each plus postage, i have heard of people using fleece for pygmy hedgehogs (soooo cute)
i sew mattress topper's to them cotton topped one's i have been using them for over a year but this design is the best, the topper's have wadding in thats all airy but it draws the urine in and spreads it out helping it to dry quicker and therefore smell a whole lot less than towels as they just sit saturated with pee on top of pee, the bottom of the topper it waterproof so it don't leak to the tray underneath.
You can sweep piggy ppops easy and just take the whole thing of and put a new one on which helps when you have a cage as big as mine i have tried lot's of bedding and these are great for me and i cant afford piggy bedspreads
(but im glad i couldnt now)
I like the green one but this is my fave
