Kawaii

As my time in Canada was now drawing to a close, my advisor invited our research group over to his house for a BBQ. Among the guests was a Japanese friend of mine who brought along his three year old son. Feeling this was the perfect victim on which to try out my very basic-level Japanese language skills, I approached him holding my advisor's kitten.

"これは小さいねこです。かわいいですね。"
This is a small cat. It's cute, isn't it?

"かわいくないです。”
It's not cute.

"....."

Where does one even go from there?
