I´ve got a mail with a nice little story:
Hi,Thanks to my son Tony and his friend, Rene Gewalt, carpenter in Stuttgart-Hedelfingen, thanks to all the creative cat owners and the pictures on your website. It gave us the idea to create this cat ladder, which is highly appreciated by my two cats. The tree trunk had to go, since it was falling apart.
Regards, Nate White, Stuttgart/ Germany
