We've been using medium size cat carrier with metal bars on front and carrying handle for the last 12 years. I fastened a one inch dowel rod through the sides in the lower half. Put a piece of indoor/outdoor carpet on the bottom. Our M2 can sit on the perch or stand on the carpet if she wants too. Cleaning is easy as it comes apart and everything is washable. Ninety nine percent of the time she goes right in. Been working for us for 30 minute trip to vet or 2 hour drive to our lake property. Have two similar but smaller carriers for our other two smaller parrots without any issues. The carry handle also is a good place to run a seat belt through and secure the carrier against moving around on car seat.
