The Norwegian Forest Cat is a breed native to Northern Europe, and over the years has adapted quite well to very cold weather. Its coat is double-layered as well as waterproof. This cat is a very sweet, loveable breed. I got the chance to care for one when I worked at Catutopia:)
The Maine Coon is America's only 'natural' breed of domestic feline. It is four times larger than the Singapura ( the world's smallest breed of cat). I owned a Maine Coone and he was huge, 18 lbs. his name was Bob. He lived until he was 15. He was one of the best cats I have ever owned. Maine Coones are very clever and they love water. Bob could always be found on the bathtub edge playing with the water while I bathed. Gosh I miss him.
Cats can be taught to walk on a leash, to teach them, The younger the cat, the easier it will be for them to learn. I personally started to train my cat and then just after a few weeks, let them have their way. I do believe that with persistence, like in anything that we do, it will pay off and they can be taught.
Pugs do not like to get their nails clipped! I found this out today when I took my dog Sumo to Bosleys to get his nails clipped and he cried and cried. The groomer said that Pugs do not at all like the nail clipping. (To bad for you Sumo) and kudos to that brave dog groomer.
