Sallyanne, I also missed this until now. I am glad that I could read already what the vet said. However I would feel worried too. A calm aby just is a contradiction in itself. If he's walking and using the litterbox however I hope it's nothing serious.

Filou does not jump as high as he did (he also has been on top of doors or falling down from the top of the cat tree because he was so crazy he lost control), so Graemer will be a little more quiet with the years.

Filou sends his coldest nosekissies and I send hugs to you.
