The charity was alerted after a member of public found the cat on a path in the park whilst out a walk on Wednesday, May 3.
Inspector Jack Marshall said: “The overweight cat was found dumped in a cat carrier along with a litter box and a bag of food.
“He’s now safely at our centre in Lanarkshire where he has been named Louie. We will easily be able to rehome him as he’s got a lovely nature.
“Abandoning an animal is an offence under the Animal Health and Welfare (Scotland) Act 2006. Anyone found guilty of doing so can expect to be banned from keeping animals for a fixed period or life.”
