An appeal has been launched to find homes for more than 100 unwanted and abandoned cats and kittens in Bradford.
Staff said they were working around the clock to care for the animals
The RSPCA said it had seen a dramatic increase in the number of cats taken in and the charity's facilities are full.
Staff said they were working around the clock to look after the animals and have appealed for help.
Centre manager Mandy Miller said: "The centre has never been as crowded. It's heartbreaking to see so many animals without a permanent home".
Animal care assistant Joanne Lee adopted her cat, Toby Tibbs, from the centre after he was found dumped in a bin next to a bus stop in Bradford when only four days old.
She said: "It's shocking that anyone could abandon such a defenceles, young animal."
Anyone interested in adopting a cat or kitten should contact the Bradford and District Branch Animal Clinic.
