instruction: Write a short paragraph about why you should not have both a pet cat and a pet bird.
response: Having both a pet bird and a pet cat is not a good idea because cats will try to hunt birds, which are naturally the prey of cats. This hunting instinct is completely normal, and it isn't fair to the cat to try to train it not to attack birds, as it is simply in its nature to do so. However, letting a cat hunt your pet bird is similarly not humane, as it will be very stressful to the bird and could lead to the bird being injured. Larger birds are also not a good idea, as the bird could cause injury to the cat if the cat tries to attack it. Overall, it just isn't a good idea to have both cats and birds, since they tend not to coexist well, and pet owners should just pick one species to have.
