MYSTERY surrounds the disappearance of six cats from one street.
Now one of the pet owners is warning people to be on their guard.
The cats have disappeared from Sarah Avenue, off Kelham Drive, Sherwood, since 2000, said Yasmin Chowdhury. Her 16-year-old cat, called Jack, is among the missing pets.
The family, including Yasmin's mum Doreen, 80, and son Oliver, nine, are all devastated by his disappearance.
He was last seen on June 26, when Doreen celebrated her birthday.
Yasmin, 48, believes someone took Jack and claims cat faeces were posted through their letter box a few weeks before he disappeared.
"It's all been really suspicious," she said. "He was a happy cat and, although he was 16. he was healthy and fairly active.
"We've had him for so long that this has really traumatised us.
"He's the sixth cat to disappear from the street and it just seems really strange because it's such a quiet area and the road is almost a dead end.
"One man on the street has put his house up for sale because his cat was one of the ones that went missing and he just doesn't like the thought of living there anymore."
Jack, is a large, long-haired, ginger cat with a white patch under his chin. Posters with his picture on have been put up around Sherwood and Yasmin has organised teams of people to look for him.
She has also reported the incident to the RSPCA. Four months on, the family are still no closer to finding Jack.
"We feel that Jack is still alive and that someone must have seen him or know where he is," said Yasmin.
"We also want to warn other cat owners to be careful when they let their cat out and keep an eye out for any strays because someone could be missing them and looking for them, as we are with Jack."
Doreen also urged people to look out for her cat. She added: "We all just miss him and want him home, it's affected the whole family."
Anyone who has seen Jack should contact Yasmin on 0115 960 7068.
