A recent study of shelter cats exposed to TV found that some cats without access to windows might benefit from having a TV as a possible form of enrichment.
The cats in the study were shown a variety of images, and the most popular programs showed shots of (not surprisingly!!!) birds, rodents and fish — natural prey for cats. Maybe such programming caters to their predatory instincts?
Next time you leave the house, consider leaving the Discovery Channel on for your cat!
