The RSPCA is appealing for information after four kittens were found abandoned in Hampshire.
A member of the public discovered the dumped cats, running loose, next to a parking area in Hursley last week.
Alert but scared, they were taken to the Stubbington Ark Animals Shelter where they were found to be underweight and with fleas.
RSPCA Insp Jan Edwards said: "These kittens were probably an unplanned litter which came about as a result of someone failing to take onboard basic animal welfare advice.
"It is a sad day when people fail their pet by not having it neutered and then when kittens come along they just shrug their shoulders and decide to dump them and let someone else deal with it.
"RSPCA animal centres are full of unwanted cats and kittens and many owners are only making the problem worse by allowing their pets to breed.
"I would urge anyone who recognizes these kittens or has information about where they came from to please contact the RSPCA so we can check on the welfare of their mother and ensure there are no other animals at risk."
Under the Animals Welfare Act 2006 anyone found guilty of causing unnecessary suffering to an animal faces up to six months in prison and a £20,000 fine.
Anyone with information is urged to call the RSPCA on 0300 1238018.
Two kittens have been found dumped next to recycling bins at a supermarket.
A member of the public spotted the pair in a cat carrier at Tesco in Hailsham in East Sussex. They were distressed and covered in faeces and taken to Raystede Centre for Animal Welfare.
They are thought to be 8-9 weeks old.
Staff at Raystede have named them Bubble and Squeak.
Head of Cattery, Jane Moore said: "They are such lovely kittens, I just cannot understand how anyone could leave them like this. They are both very friendly and have obviously been socialised well."
Anyone interested in re-homing the kittens or making a donation should call 01825 840252 or visit www.raystede.org
