Sparkle has caught birds and brought them in several times. Some vets are licensed for wildlife; my vet is not and they get VERY upset when I walk in with the bird. But they send me to the vet down the street who IS licensed, and they treat the bird. Two had to be euthanized, one was rehabilitated and then set free. It didn't cost me a thing. Something to keep in mind if you have a hunter! I think they take mice too, being licensed for wildlife. But the only two mice my cats ever caught, one got away and dashed off and the other was dead when I got to it, so I never had to take one in to the vet.

My cats are INDOOR cats. Sparkle caught one bird when we lived in the apartment, on the third floor! She snatched it out on the balcony and brought it in the cat door! The other times, the cats are out in the back yard with us as we garden. We watch and keep them in the yard, away from cars and any dogs who may be loose, but we are always surprised when they catch a prize!

Just another aspect of cat ownership!
