Local firefighters have staged a daring rescue mission to kick off kitten season, saving a three-week-old kitten trapped inside a house wall.

RSPCA WA inspectors and Department of Fire and Emergency Serviecs firefighters were called to a Queens Park home on Monday after two tiny kittens were heard mewing in the roof space.

One had already been retrieved by a neighbour when the rescuers arrived, but her sister remained trapped.

RSPCA WA trainee inspector Amanda McMinn quickly realised the kitten was stuck inside a wall cavity.

She quickly called DFES for help, and after several hours of work they carefully removed bricks from the wall to retrieve the calico kitten.

“She was in an internal wall cavity that was really long, complicating the rescue even further,” Ms McMinn said.

“The DFES crew were fantastic. They worked for ages, smashing through the wall with a hammer while at the same time being careful not to injure the kitten.

“We had to encourage her to come out by letting her hear her sister’s little meows. She was understandably a little overwhelmed after her ordeal, but thankfully she was safe.”

The female kittens have been named Kiki and Blaiyke in honour of two of their rescuers, Keith and Blake. Both are now recovered and settling into foster care.

A few days later, RSPCA received another call about four kittens stuck between buildings in Midland.

Just days old and trapped at the bottom of a narrow crevice, the kittens were unable to be freed without specialised equipment.

DFES was again called to free the kittens, who are now being looked after by a foster carer experienced with neonatal kittens.

RSPCA WA head of corporate communication and education Louise Rowe said this “kitten season” served as a reminder for pet owners to keep an eye on their cats.

“Even though it’s been a mild start to spring, it seems as if kitten season — when breeding spikes during the warmer months — has already started,” she said.

“This time of year puts huge pressure on cat rescue and welfare groups. Our plea is for owners to prioritise desexing their cats and kittens, and to keep pets safely contained to their property.”
