Unsolved Cat and Dog Mystery Day!

Our friends Maggy and Zoey from Zoolatry have proclaimed today UN Solved Cat 'n' Dog Mystery Day.

Tamir says our UNsolved mystery is about these two cats.....

They look a little like my sisfurs.....

but they don't taste like them....

Hey....my sisfurs are here investigating this mystery too!!
