Now, either you do organize help. It was a street thing in the town? Thus somebody at the towns technical authority, taking care about such.
Or, simply to saw the cat out. Get a metall-saw and just do it. Or, anybody with a saw and knowing how to use it...
A friendly police officer/constable you talk with may help, but I really dont think 999 would send a car... A friendly fire man would also be fine - they are used to help out. Try to phone the station of the fire brigade and talk with them.
If you cant do anything - help it go on. Not pleasant but better than leave it there for slowly dying. YOU found, YOU must help in some way.
Good luck!
