PetMate Sky Kennel, size EXTRA LARGE (40" x 27" x 30") **
http://www.petmate.com/sky-kennel

Suitable for crate training at home or for pets traveling by air as cargo. Compliant with IATA airline regulations. Comes with an absorbant liner, two plastic water/food bowls (required for travel) that clip onto the door, and extra zip-ties. The top half of the crate comes off and nestles into the bottom half, allowing it to fit in the backseat of most sedans when disassembled. Purchased in March and used for just one cross-country flight. In very good condition. Selling because I no longer need it and it's too big to store conveniently.

How to measure your pet and choose a crate size:

** Note: If you're in the market for an airline crate but don't think your dog needs such a large one, please do take a look at the dimension requirements at the IATA link above before passing this up. Height (rather than weight) is likely to determine crate size requirements. For instance, my dog weighs just 45 lbs and I think of her as medium-sized, but she needs the extra large crate because she's tall.

Selling for $90. (retails on Amazon for $144 and at pet stores for $175 and up)
Available for pickup in downtown Palo Alto.
I'll deliver to campus for free or to addresses in Palo Alto/Mtn View/Menlo Park for an additional $10.
