Also known as Recycle-a-Rodent, CavyRescue has been "the UK's first and only dedicated rat rescue charity" since it registered as a charity last year.
But it isn't just about rats. The organisation was founded by Jason and Stella Hulott to rescue, rehabilitate and rehome small animals. It also aims to educate pet owners on small animal healthcare and welfare.
The CavyRescue website includes profiles of unwanted 'furries' around the country that are in search of a home. Degus, rabbits, hamsters, rats and guinea pigs take up residence with the Hulotts in Kent while they await adoption into loving and caring families. Those unable to keep a rat of their own can sponsor a rat that is not mentally or physically stable enough for adoption, for £10 a year.
The average monthly cost of caring for all the shelter's permanent residents is £200. However, this does not include veterinary bills, which amount to about £15,000 a year and are covered by the Hulotts and by donations.
