Black cats are half as likely to be adopted as other felines because they’re associated with bad luck, an overstretched Perth animal shelter has found.

The Cat Haven says black cats often remain at its Shenton Park facility longer than others – some for months – which is a big expense for the charity and takes its toll on the overlooked feline.

“They are cooped up in a cat pen with no exercise and they can get quite depressed,” marketing officer Chandra Woodley said on Friday.

The Cat Haven is holding a Black Cat Weekend from June 13 in a bid to re-home their dark moggies, with a reduced adoption fee of $39 for cats and $100 for kittens.

The facility says it is in crisis as it is full.

Here are some of the The Cat Haven’s cats up for adoption:

Guinness (Gus), male, three years old

Portia, female, 2.5 years old

India, female, 2.5 years old

Piper (female) three years old

Skyla (male) seven months old
