It is more comfortable talking the suitcase with my cat in it than any other "cat backpack" I have purchased. Normally after carrying him in a conventional box I would end up with wrist and arm pain. But now I have no complaints.
It is spacious, comfortable for both me and my cat. My cat HATES, I mean HATES going in bags but she felt comfortable going in it from the day I got it. It was also easier to have her travel than other times. I could buckle her up easily and had a safe and comfortable travel.
I needed a bag to accommodate a bigger kitty so I dug around online and found this one! I have debated on buying a carrier like this for years. It is super well made and my cat really likes it.
