A breed of cat kept as a domestic pet in the Federation, one of which was the first pet Geordi La Forge owned as a boy of eight.
The Circassian cat is a feline kept as a household pet. It is known from Geordi La Forge's recollection in the episode Violations.
When the Ullian historians aboard the Enterprise-D demonstrate their ability to recover lost memories, the conversation turns to the things people remember from childhood. La Forge recalls that his first pet was a Circassian cat, which he was given when he was eight years old, and describes it with obvious affection.
Nothing more is established about the animal's origin or appearance. La Forge's fondness for cats is seen again when he borrows Data's cat Spot in the episode Force of Nature to find out whether he would like to keep one himself.
