Thunderbirds are supposed to be 'go' - but Lady Penelope has been left behind at Battersea’s Old Windsor centre.

This Lady Penelope though is not a marionette but a five-year-old cat, who has found she is the one in need of rescuing.

Sadly, it is taking longer than expected. While the average stay for a cat at Battersea is just 22 days, Lady Penelope has been there more than six months.

She has not been able to find a family because she has a condition called Feline Immunodeficiency Virus (FIV) – a disease which cannot be spread to humans or other animals.

Battersea Old Windsor’s Cattery Team Leader, Caroline Shilton said: “Many FIV+ cats like Lady Penelope can go on to live long and happy lives - as long as their health is looked after.

"However they do need a particular type of home - with an enclosed, cat-proof garden to prevent them from leaving and other cats from paying them a visit to keep both parties safe.

"It’s important FIV+ cats don’t meet other felines as - if they fight - they could potentially spread the virus through their saliva.”

“Lady Penelope is a wonderful cat. She’s very affectionate, with a sweet and sensitive nature. She is looking for a quiet life, as the only pet in the home.”
