The giant cat litter tray is 20.5" x 17"

The answer partly depends on how old the kitten is. If it's been living outside for awhile, it might find dirt to be more familiar than shredded paper. Another option is to buy a disposable cat litter tray. They're inexpensive (e.g. $4) and I think you can find it at most large grocery stores and drugstores in addition to pet stores. Most outdoor cats seem to understand what cat litter is for and adapt quickly. Good luck!

CAT LITTER TRAY SCOOP Pet Kitty Litter Boxes Scooper Poop Cleaning Plastic Tool

very useful, like all Pet travel store product I got, the only thing is that my cat does not eat much during flight and I take him in-cabin, which doesn't leave him any room for anything, but i guess for those who travel cargo in a pet crate these would be ideal, especially for an adult cat.

They also recommend using special blue crystals for litter to help eliminate odors.

The Omega Paw Self-Cleaning Litter Box cleans in just seconds without scooping – but this time you’re doing the rolling, rather than the litter box being mechanical in any way. Inside the litter box a grating separates the tray where the cat goes from the area where waste collects when you tilt the box. It’s not mechanized, so it’s a less expensive option, but it also doesn’t remove waste soon after your cat uses the litter box – so it may not help with odor issues any more than a normal box.
