“Basically, no matter where you are in the world, keeping your cat indoors is a great way to keep them healthy from infectious diseases,” Chalkowski stated by way of summary.
This is especially good advice, she went on to say, “considering that many of the pathogens cats carry can actually be spread to humans”. Other domesticated animals can transmit disease to their caretakers—dogs, for example, spread rabies, and cattle can carry Cryptosporidium parvum, a parasitic disease that attacks the intestinal tract.
Wild cats were likely first drawn to human communities in search of rodents, and were domesticated in upwards of 5,000 years ago. In ancient Egypt, they were associated with the gods and prominently showcased in hieroglyphics.
There are about 90 million pet cats in the United States, and an estimated 500 million worldwide.
