Nellie is microchipped, too...they've already done it at the shelter, but when we got her we had to have her registered at two of the most important animal organizations over here...

In the beginning Nellie wore a collar as she's allowed outside, too, but one day I've witnessed how she got stuck in a shrub with that collar, she was crying and went berserk and I was so happy that I've been around to help her...so please be very very careful concerning collars!!!

My vet's cat has a tiny blue earbutton, looks like one of the things the Steiff plush teddies wear, just to give hint that this cat is microchipped...the cat doesn't seemed to be bothered by the button and it's not that dangerous as a collar!

Most of the shelters and vets work with the microchipping here and I think it's the very best for the cat, because a tatoo may vanish over the years (especially in black cats), but of course the cat has to be registered!!!
