Perhaps best known for their fluffy coats, Selkirk Rex cats can trace their origins back to Montana, where the breed was spotted for the first time in 1987. 

The Selkirk Rex can come in long and shorthair varieties, and are notable for their heavy-boned frames.

Their chilled-out personalities make them great for families with kids. Purchasing one will set you back $600-$1,500 (£506-£1.3k).
