i did it once when my cat lalang was about a few months old. it was hari raya vacation, no one is at the hostel. at that time i was naive, no idea about cat boarding, fearing my cat getting famished

i used a bag and put it with some towel. however, i put my cat to the sleeping pill first... however, i think that ride must be quite uncomfortable for my cat...

from my hostel to upm bus stop - motorcycle
from bus stop to serdang commuter - taxi
from serdang to tasik selatan - commuter
from tasik selatan to pudu - lrt
from pudu to kluang - bus (of course!)
kluang to home -car

however, only few people did notice i brought my cat as he was sleepy... the girl sitting beside me in the bus even confessed she brought back a rabbit the same way!

thinking about it, that tom-cat is the most adventurous of all my cats

the lady that gave me that cat brought hers from penang to kl by bus too, in a carrier and drugged... she even bought a bus ticket for the cat! so basically the bus driver don't complain

p/s : i'm not encouraging huh. just telling my experience
