what's that smell?

have you ever been perplexed to find a cat and a rat living together under the same roof? it sounds like tom and jerry, but apparently it happens because rats get used to the smell of a cat over time and react differently to them. a new scientific study has found out that rats can identify the scent of a new cat introduced into the same area and differentiate it from that of other known cats.

so basically a lazy cat is even less of a threat to a rodent. grrreat.
