The Siberian cat hails from Russia, and is one of the cat breeds that are considered to be a good choice for allergy sufferers, as they produce less of the Fel D1 protein that is a common allergenic trigger in people who are susceptible to it. The Siberian cat is generally considered to be a sturdy, chunkily built cat, with females on average weighing 8-12lb and males up to an average of 17lb and sometimes significantly more.
