Appeal after 44 rats and 15 rabbits found dumped over Easter weekend
One of the baby rabbits had to be humanely killed due to severe leg injuries.
Almost 60 rats and rabbits were found dumped in two separate incidents over Easter weekend.
The Scottish SPCA is appealing for information to try and trace the owners after rescuing the animals, one of which had to be humanely killed due to its injuries.
Several of the rats were newly born and two of the rabbits are pregnant.
The animal welfare charity was first alerted to the abandoned rats by a member of the public on April 3.
They were discovered within a cabinet at a lay-by on the A68 between the Edinburgh city bypass and Dalkeith.
The rats were abandoned inside a cabinet
On April 4, Scottish SPCA welfare officers received a call about 15 rabbits abandoned in the Langton area of East Calder, in West Lothian.
All of the animals are now in the care of the Edinburgh and Lothians Animal Rescue and Rehoming Centre in Balerno.
Assistant manager Kenny Sharpe said: "The rats were left inside a cabinet in the lay-by. There is a mixture of male and female rats, some adults and some newborns.
"Thankfully they are all in good condition despite the circumstances. We will care for the rats until we can find them new homes.
"We think the rabbits were dumped and then spread themselves out as they were scattered over several gardens. It's likely more than one person was involved given the volume of rabbits.
"There are three adults, two of which are pregnant. There are also six bunnies aged around a week old and five ranging from six weeks old to five months old.
"Sadly, one baby rabbit had to be put to sleep due to a severely damaged back leg.
"This is possibly a case of breeding gone wrong and we are very keen to identify who abandoned these rabbits.
"Anyone with information relating to the rabbits or the rats should call our animal helpline on 03000 999 999."
Mr Sharpe added: "Abandoning and causing an animal unnecessary suffering animal is an offence under the Animal Health and Welfare Act and anyone found guilty of doing so can expect to be banned from keeping animals for a fixed period or life."
