The RSPCA is investigating a series of incidents across the East Midlands in which animals have been shot and injured with air guns.
Leo needed to have his foreleg amputated
The latest victim is a cat called Leo from Sherwood, Nottinghamshire who had to have his leg amputated after being shot with an air pellet.
An RSPCA spokesperson said people could face a six-month prison sentence and/or a £5,000 fine for harming animals.
The RSPCA has dealt with 43 air weapon attacks in the region since 1 January.
RSPCA inspector Laura Kirkham said: "This poor cat [Leo] suffered a huge amount of pain and distress.
"These attacks are often carried out by someone who is deliberately using an animal as target practice."
She urged anyone with information about the attack on Leo to contact the RSPCA.
