haha..last time i also like to add more and more tunnel for my hammie...but..adei....they love to lepak - lepak at the tunnel + poo and pee there..and they also love to sleep in the tunnel..it is hard for me to clean the tunnel.i am taking more than 1 hour to clean up all thie mess..somemore, that time i got more that 6 hamster in 1 cage ...
end up..i simpan balik the tunnel..just use the main cage only..hikhik
but it is very nice !!!
