Veterinarians have evening hours.
Your kitten wont be able to disturb the whole movie with its
crying. Hell, you dont even have to take the kitten with you,
and if you dont, you dont even have to worry about whether or
not the sitter is available tonight.
Your kitten wont grow out of those cute but expensive clothes
within three months.
Kittens look cute if they havent had a bath in a month.
You probably dont have to lie awake nights wondering how
youre going to finance your kittens college education.
No one will accuse you of being an unfit mother if you dont
want to breast feed your kitten.
Dan Quayle cant accuse you of destroying the moral fabric of
the country if you arent married to the father of your kitten. In
fact, nobody will ever ask you if you know who the father is.
No one will question your abilities to function normally at
your job when they hear you just got a kitten.
You only have to change the litter box once a day.
