(the 1st link is a wire-service report, the 2nd link has a small photo
and additional background info)

The gist of the above articles is that a stray cat was turned in to
San Francisco's Department of Animal Care and Control. They scanned
the cat, found a chip, and discovered that the cat belonged to a woman
in Bradenton, Florida - 3000 miles away.

The cat, a black short-hair named Cheyenne, was adopted by a woman in
Bradenton in 1997. A few months later she (Cheyenne) disappeared. The
woman hung fliers and ran ads, but had no luck in finding her cat.
Until she got a call from her local shelter earlier this month...

Cheyenne is in very good condition. Authorities think that a former
neighbor probably decided to keep Cheyenne for themselves, then moved
to SF. No one has contacted Animal Control claiming to be Cheyenne's
owner, but the microship provides legal identification of her true
owner in Florida, wh retains legal rights. Interestingly enough, the
shelter Cheyenne was adopted from was one of the first in Florida to
microchip its animals.

They're currently trying to find a way to get Cheyenne, who is now 10
years old, back home. Animal Control can't afford to ship her to
Florida, so workers there have been looking for a volunteer traveller
to carry her on a plane trip with them.

SF Animal Control's website is at

There's a link to information about Cheyenne there.

They've also got a link to Cheyenne's Bradenton animal shelter:
