An "unprecedented" number of pets have been left in the care of the RSPCA at a branch in Buckinghamshire, the animal charity has said.
The Blackberry Farm Animal Centre, near Aylesbury, took in 178 animals during September.
During the same period in 2009, 81 animals were brought into the centre.
Centre manager Julie Allen said: "We just cannot stress enough how dire the situation currently is. More and more people are just dumping their animals."
She added: "Sadly the fact is we are getting more animals coming in than are going out and being re-homed.
"It is depressing and heartbreaking. We can care and nurture these animals. But what they desperately need is a good, kind owner to look after them."
