I'm a cat person.
I'd also remind people that cats are the first and most important of the three great "companion species" to humanity. While sort of irrelevent, keep in mind that cats have been integral to establishing civilization.
Why? you might ask. Weren't other animals more useful? What do cats do except be cute and purr?
Well the answer is quite simple, they hunt vermin. Especially at lower tech levels vermin were a huge problem in any large gathering of people. Rats and such would get into supplies of food and taint it, both stored on land and in the holds of ships. There were also problems with disease, and while cats were incorrectly blamed at the beginning of "The Black Plague" they were also eventually part of the solution.
Without cats, arguably civilization would have failed on any large level. This is how they became prolific among people. It's also ironic how in some urban areas people go to animal services to chase stray cats and such away, and then a while afterwards have an even worse problem with rodents. The prescence of cats (at least not overly domesticated ones who cease to even consider hunting) generally tends to be inversely proportionate to the vermin population in any area.
The other two companion species in order of importance are dogs (help in hunting, and protection), and Horses (heavy labour, and rapid travel). Horses being the least useful today due to innovations in machinery which can cause people to travel faster and move weights far more efficiently.
At any rate if humanity is obligated to preserve any species, or choose animals to bring to colonize other planets, those are the three closest to humanity and most responsible for helping us with our success overall.
The point of this propaganda piece is that I think a lot of people miss the point of cats, why they were domesticated, and how bloody useful they have been through history (and arguably continue to be, even if our food and such is more safely stored).
