pet story expansion

Im on level 51 and my pet shop is getting crowded, why can't I expand anymore?

Unfortunately there are no more expansions. Once you have expanded and you do not see the option to expand any more, you are then maxed out.

Thank you!!

is it hard to allow expansion? no expansion, i'll incline to play less or stop playing the game.

I totally agree. I have for the most part quit playing because I can not expand and have to keep storing animals to play. Couldn't you develop a second floor or allow more ground to be bought?
