Checking to see if any of these cars could effectively haul a cat/trailer. This will be a disassembled cat, so the width of the trailer will be around 7 feet, not the 8'6" like the "normal" cat trailers.

I guestimate the trailer, cat, and equipment will be around 900-1000 lbs. max.

Here's the choices:

Chevy Aveo - 103hp - 107 ft. lbs. torque
Kia Rio - 110hp - 107 ft. lbs. torque
Toyota Yaris - 106hp - 103 ft. lbs. torque
Honda Fit - 109hp - 105 ft. lbs. torque
