I cannot say enough positive, kind comments about this pet carrier and taxi! I bought this carrier to allow my pet cat a larger space as he had to be kept overnight at my local veterinarian's office, in order to get his neutering first thing in the morning. I hoped that he would have a space that was big enough to both kennel him and give him adequate space as well. He seemed to love it! Keep in mind I bought the larger unit and was able to place a corner ferret litter pan in the corner, littler, and still have room for a blanket, food and water tray on the front grate, and a crinkle ball toy with room to move. My cat did not enjoy the trip to the vet but seemed to like the carrier despite this traumatic event. I also liked that taxi was easy to assemble, was moderately prices, and fit very well in my trunk. I would definately buy this taxi again for other members of extended pet family.
