Adoptable co-founder Ashleigh Dark said the organisation was approached 12 months ago by a couple that had allowed their stray cat to breed.

“Unfortunately that stray was entire and as cats are so adept at doing, she had kittens, who had kittens, who had more kittens,” she said.

“Before they knew it they were inundated, with over 40 cats living under the house. 

“A concerted effort was made by a number of our volunteers along with the grateful family who trapped, desexed and re-homed these sick and unsocial cats.”

Ms Dark said the final female cat, which was the original mother, was desexed on Monday. 

“We are thrilled to have been able to complete such a monstrous project that has resulted in providing so many animals with long, healthy and happy lives, where they will no longer contribute to the oversupply of cats and kittens,” she said.

“We hope this story inspires more people to step up and choose to make a difference in the lives of stray and unwanted animals in our shire.”

Adoptable team member Lauren Del Rio said it was still a big problem which must be closely monitored.

“It is frustrating when there are repeated offenders who just simply choose not to desex their cats,” she said.

“It is something we need to try and manage and try to minimise cat owners who cannot provide cats with a better and safe home.”

Ms Del Rio said leaving pets entire can lead to a range of health issues which were easily avoidable by desexing pets at a young age. 

“Pregnant cats can get kittens stuck and sometimes the kittens can come out the wrong way and die,” she said.

“Some pregnant cats will also need a cesarean which is a huge expense, a minimum of $600.

“Cats that are not desexed also roam around at night which increases their chance of being hit by cars and increases their chance of becoming infected with feline aids after fighting with other cats.”
