"This is not to diss dogs. They have their value, too, as mentioned above. However, they are much higher-maintenance companions (including often smelling really foul unless bathed regularly by their humans), and this makes them less suitable as animal companions for many people.   Having a dog is a bit like having a kindergarten-age kid.   They may not be all that destructive to your house and home, but they cannot be left long on their own, for their own safety and health.   Cats, on the other hand, are more like teenagers.   Much more independent and less likely to starve, mope, or need help with their daily routine - but also more likely to trash the furniture when you're not there."

Cats stink. Anyone who has ever lived under the same roof with a catbox knows this.

Companion? The cat doesn't care if you live or die. They are egotistical parasites. Like celebrities, or politicians. Or poorly raised teenagers.

The only thing cats are good for is catching vermin, and they'll only do this to avoid starvation.
