hamster or guinea pig??

yesterday i was at my sister's place for overnight. when i walked into the door i was greeted by a pair of eyes. i peeked inside its cage and it turns out to be a small hairy creature and it turns out not alone. its FOUR of them!!!

i was thinking.....since when did my sis is fond with this kind of pets? idk.
*die pon jenis penggeli macam aku jugak*

nak tengok muka haiwan berbulu ni??

- nampak macam die sengsorang kan? ciss -

- and this is my hands hold the most active one! -
