We will be moving cross country and ordered this for our four cats (one is a big boy). This kennel is huge. I have a mid-size SUV (Terrain) and had to scoot the back seats all the way up, fold them down, and turn the kennel sideways to fit...barely. It just misses the hatch door. But it is big enough for a small litter box and though a little snug, the cats should fit comfortably.
