Wow, you're lucky!

My grandma has a male Siberian cat named Shy, when she lived in Australia. And then she brought him back to Malaysia, but the news ain't as big as your's, but he's an orange+white siberian. I don't have a picture of him, but he passed away a few months ago.

He's supposed to be 17 years old this year, by the way, even OLDER than I am! And he's toilet trained! He pooped in the toilet (but he still urined in the litter box. haha) Maybe you could teach your's to do that!

Do you think I should still email the Matreshka cattery and ask them if they could reserve a cat for me? We'd love a Siberian cat to replace Shy. We miss him very, very much.
