<human>: How long can I keep my cat inside before it gets sick?
<bot>: It depends on the individual cat and their health, but generally cats should be allowed outside at least once a day. Cats that are kept indoors for too long may become depressed or bored, so you should take them out as often as possible to give them some mental stimulation. Additionally, cats need to have regular access to fresh air and sunshine in order to stay healthy.
