The SPCA says Tommy, a five year old cat, was let out of his house in Lackawanna Thursday morning.
A few hours later, he was spotted in his yard with the arrow.
The cat was alive, and rushed by his owners to Elmwood Small Animal Hospital. There, it was determined the cat be euthanized for humane reasons.
Now the SPCA wants to know who was responsible.
