This wasn't of course meant to be a birthday present!!!
Fister is such a handsome and wonderful guy I am sure this wasn't his intention!!!
I hope you had a great birthday, though and that Fister is doing fine again!!!

And what a naughty boy this Ib is!!!
I am so sorry to hear that he's the reason that cats aren't allowed in the yard anymore...but unfortunately cats are attracted to sand so much...
I've noticed that the sandbox is already covered, wouldn't it be possible to cover the rest with a different material than sand, for example grass?!

Then everyone would be happy...the children, the cats and even the landlord!!!
