I can highly recommend a pet carrier I purchased from Amazon on Feb. 10, 2013 ($40.27). It is known as Petmate Two Door Top Load 24-Inch Kennel, which is constructed of steel and plastic. It also has a secure carry handle. I had to put the carrier together myself (and was quite angry about that when I received it) but it was actually very easy. For me to say that it was easy is significant because hate having my time constrained by having to assemble anything. The reason I can recommend this carrier for a large cat is because I used it again on January 11, 2014 to take my male cat to the vet (he weighed in that day at 17.55 pounds) and there was still plenty of room in the carrier for him. I have a small car, a Honda coupe, and the carrier fits nicely in my car in one of the two rear seats. The other reason I like this carrier is because it can easily be washed out if a cat has an accident. I am also short (5’2″, somewhat handicapped with advanced osteoarthritis and generally use a cane). However, I do have strong arms (like to lift weights). I can park in the handicap area of a PetSmart store and manage to carry Whitie to the Banfield Hospital at the rear of the store without any assistance from anyone. LOL. Attached is a picture of the carrier.
My cat, “Whitie,” seems to feel very comfortable in the carrier because he likes to get into the carrier while it is sitting out in the living room.
The other carrier I like for a large cat is the Nylabone Cozytime Pet Home & Carrier. It can actually hold a small dog up to 20 pounds. The carrier is collapsible and there is nothing to assemble. The front door is removable. The carrier also has a clear sky dome top which provides plenty of natural light and can be opened. This carrier folds flat for storage and also has a secure grip handle on top. It is great for someone with a larger vehicle than my coupe. I have two of these carriers and use them as loungers for my two Ragdolls. I have placed the two carriers on a large table directly in front of a south facing patio door. Both cats go into these during the day and sleep. I removed the front doors — no tools are necessary — and keep the doors put away in a closet. The cats can enter and leave these carriers as they wish. They are actually beautifully carriers. However, I was unable to secure them to the smallish bucket seats at the rear of my car. If one has a high profile vehicle, SUV or other, these carriers would be fine for transport. They are not, however, approved for air travel. Attached is a photo. You can purchase these from Chewy.com ($53.15).
