Dogs and cats love to go outside.

Dogs, owing to obvious needs, have to exit the house and love their walks. But do walks provide enough exercise? Obviously, just letting your dog roam free is dangerous, especially in areas with even moderate vehicular traffic. Besides, letting a dog roam free is illegal in most towns. It wasn’t like that years ago when dogs roamed small towns, so much so that just about everybody knew their names.

As for felines, there are “inside cats,” with their human parents keeping them in the house to ensure their safety.
