Two sheep have been stolen from Perth’s RSPCA headquarters.
It comes after RSPCA inspectors took 71 ill-treated animals from a property on the outskirts of Perth on Friday.
Sheep, dogs, cats, birds, guinea pigs and rabbits were found to be living in filthy conditions without adequate food or water.
RSPCA spokesman Tim Mayne said on Sunday that the charity was reviewing CCTV footage from Friday night and had contacted police.
“The sheep are unwell and need urgent veterinary treatment,” he said.
“We want to ensure the sheep are returned safely and quickly so we can continue with their medical treatment.”
The RSPCA is currently at crisis point after a massive influx of animals pushed the shelter beyond its capacity by about 200 animals.
There are currently more than 370 animals on site.
Anyone with information about the missing sheep is asked to call the RSPCA on 9209 9300.
