What's the scientific name for the domestic cat? I've seen both Felis
catus or Felis sylvestris catus.

"The current method of mammalian nomenclaure does not specifically address
domestication, so some domesticated species have the same name (ferrets,
chickens, turkeys, pigs, etc.), while others have different names (dogs,
cats, etc.).  Since this non-uniformity reflects tradition, non-scientific
bias, etc., and is not based on any particular scientific principle, *ANY*
designation of a domesticated species is theoretically incorrect... it
is actually just as correct to label the ferret 'Mustela furo'
instead of 'Mustela putorious furo' as it is to label the dog 'Canis
familiaris' instead of 'Canis lupus familiaris' or the cat 'Felis catus'
instead of 'Felis sylvestris catus.' One domestication scientist has
suggested all domestic animals lose their current binomials and be labeled
'Mustela putorius f. domesticus' or 'Canis lupus f. domesticus' (f. means
forma).  Others suggest domesticated species simply be labeled 'Mustela
domesticus' or 'Felis domesticus.'  And still others think domestication is
evolution, so domesticates should get their own binomial, such as 'Mustela
furo' or 'Canis familiaris.'  The debate is yet to be resolved."

According to my cat, the proper designation is "Boss".

My cats agree with Missy's cat. "Boss" or "Your Highness" sum it up.

Here's an interesting page that touches on the subject:

tigers are Panthera tigris
if u see anything with "felis" in it, then it's a cat
