She was found in the bag by a member of the public, near their home on Albany Road, at approximately 4pm last Wednesday (6 June).
It was clear an attempt had been made to trap the kitten within the handbag, as the zip was completely done up aside from a very small gap.
The discovery has led the RSPCA to launch an appeal for information, eager to decipher how the kitten came to be dumped in such dangerous circumstances.
RSPCA continue to provide care for the “very sweet, friendly” kitten – who is thought to be 20 weeks of age, and – fortunately – is progressing well
Annie Simmonds, RSPCA inspector, said: “I feel shock and dismay that anyone would deem it acceptable to treat a kitten in such a cruel and dangerous manner.
“This poor, young female kitten was found in a zipped-up handbag on a lane near Albany Road, in the Roath area of Cardiff.
“She must have been absolutely terrified – but thankfully, this very sweet, friendly cat is doing well in our care.
“We’re desperate for anyone with information related to this awful abandonment to contact our inspectorate appeal line.
“Calls can be made on 0300 123 8018 – and we’d urge anyone who knows something about how this kitten came to be trapped in this bag to contact us.”
