Domestic Long Hair is a coat description, not a pedigree. These are mixed-ancestry cats with medium to long fur, and they turn up in every color and pattern, from brown tabby to calico to smoky black. Most weigh 8 to 15 pounds, though the fluff can make a cat look bigger than she is.
Because there's no breed standard, temperament and energy vary from cat to cat. What they share is a coat that needs brushing a few times a week to prevent mats and hairballs, plus the sturdy health that often comes with mixed ancestry. In a humid Georgia climate, that coat is the main thing to plan around, so meeting a cat and seeing how she tolerates brushing tells you more than the label.
