A mystery cat shaver is said to have clipped the fur from around 12 animals in a string of bizarre attacks.
The RSPCA is appealing for information after some cats in the Cotswolds are said to have been attacked up to four times each.
Shavings have happened within a six-mile radius since November and, on each occasion, the pets have had a piece of fur removed, often being left with a bald patch.
A spokesman for the RSPCA warned: “Shaving a cat in this way could cause huge distress to both animal and owner.”
Gloucestershire Police confirmed they had investigated reports of a cat returning home with shaved patches in its fur and carried out enquiries around the local area.
A spokesman said: "An element of animal cruelty could be considered if the cat was injured or distressed. But if the cat keeps coming back home with shaved patches, this would suggest it keeps going back to whoever is doing it by choice.
"It could also be classed as criminal damage as the cat is somebody’s property. Ultimately, if the perpetrator was found, officers are likely to give them words of advice and find out why they are doing this to establish a motive."
Anyone with information should call the charity on 0300 123 4999 or to contact the police.
