     The kitten was rescued, but didn't make it out of surgery in one piece.

     The veterinarian at Laurel Oaks Animal Hospital in Kingsland, now acting for the kitten, says she sees

animal abuse more often than you might imagine.

     This kitten is playful and affectionate, but he has already seen how cruel a place the world can be.

     Dr. Julie Clark Blount is the veterinarian treating the kitten now, "I think they were actually kicking him

or throwing him or something of that nature," said Blount, "They had damaged the whole bundle of nerves

that are up in the armpit and control the functioning of the entire leg, and it's not something that would get

better over time."

     Blount says they were forced to amputate his front right leg, "It doesn't seem to bother him at all and he

runs and he plays and he loves attention and he's pretty spoiled already, and he's eating like a little pig, and

doing fabulously for us," said Blount.

     Doing well, but Blount says other pets out there never survive abuse.

     "He's one of the lucky one," she said.

     Blount says unless abusers like him are caught and prosecuted, they could go on to bigger and worse

things. 

     "We with there were more strict laws to protect animals because if they're doing this to pets, then what

would then end up doing to people, or kids, or anything else later on down the road?" wonders Blount.
