You put a kitten in a small room with a litter box and forget to put in a small bed...?
One smelly kitten....

Why I made that equation? I'll tell you a small story.
My dad came in to the family room, holding our new kitten in his hand (yes, hand) and put her on the couch next to me, saying, "Poor Kitty." I didn't bather with the remark, thinking that the kitten has being alone wandering in the house, wondering where her humans are at. I was only half right, on the alone part. Then my dad went back to the pantry from where he got the kitten, and I smelled something stinky and stingy wafting up to my nose.
"Dad! She smells gross, like litter and pee!" I hollered. I saw my dad come back out of the pantry with a Fabreeze spray.
'Unbelieveable.' I thought.
Then he proceeded to gently spray the kitten's body, shielding her head from the spray.
I couldn't help but laugh.

I laughed, and I laughed even harder when he told me why the kitten smelled bad. Turns out that someone put her in the bathroom with a litter box, but neglected to put a bed in there as well.

I'm sure you can guess the rest.
