I had to leave my residence during hurricane Sandy and didn't have adequate carriers for my 4 Persians, which made it difficult to manage. I found the IGO2 Traveler Carriers and checked the pricing at local pet chain stores as well as at other on line sources, and Wayfair had the best pricing. This carrier is extremely well made and sturdy, and doesn't tip over in the front like others do. Removable washable floor mat, carrying strap, backpack straps, and telescopic rolling capabilities are great. Best of all, my huge 17 lb, tall Persian can sit up straight, stand, or lay down in this roomy Traveler model. I liked it so much I bought three others (smaller models) for my other cats. Now I can easily maneuver them all quickly and easily into the car (they also have wheel covers so they don't damage car seats). Will last a lifetime and it was a good investment for my pets.
