Stroking the motherless grey kitten on my lap, I look down and see a thin, rangy tom cat winding around my legs.
For three years Major has survived on scraps from the local Chinese, and he is covered in wounds. Yet he is so friendly, someone must have loved him once.
Sadly, those days are long gone. Like so many of the cats around me, Major was abandoned by his owner and left to the care of the Celia Hammond Animal Trust (CHAT) in East London.
This cat and dog rescue centre, opened by the former Vogue model in 1986, receives 30 or more calls a day reporting abuse or asking for help.
CHAT never turns away an animal or puts down a healthy cat, but for the first time Celia tells me she is unable to cope with the demand.
Sadly, this situation is replicated all over the country, with animal shelters straining at the seams as they attempt to care for an estimated seven to ten million abandoned cats.
