Nikita and Leon, a couple of adorable black shorthair crossbreeds, have been inseparable across their entire lives, so when they arrived at the RSPCA in Northamptonshire, staff were determined to find them a new home together.
Staff launched a campaign to get them a new home. Posting some snaps of the brothers on Facebook, they wrote: "Poor Leon and Nikita found themselves in our care at the grand age of 21.
"They are bonded brothers and were signed over to be rehomed as they were not coping with family life.
"They are both in fairly good health but Nikita has just been diagnosed with hyperthyroidism.
"He will need blood tests over the next few weeks/months at our vets to check how he is responding to medication
"Due to their age, we were keen to get these lovely boys settled into a new home asap.
"Leon and Nikita are an affectionate pair who enjoy chin tickles and human company.
"They are looking for a quiet home with no children."
And the cute pair quickly won over hearts, with offers flooding in from all over the world.
Julie Clifft, from the RSPCA Northamptonshire adoption team, said: "It's been pretty crazy.
"We have had over 100 applications for them from all over the place, from America, Cornwall and Cumbria.
"Nikita has been diagnosed with hyperthyroidism and is stable but needs to stay close to his vet for checks.
"We wanted to keep them within the local area but some people haven't read that bit.
"We really wanted to keep them together in Northamptonshire and we're delighted that
has been possible.
"They've been really, really popular. We expected lots of applications but not hundreds.
"It's great because although they are old, we never put a healthy pet down and they deserved a new home."
Nikita and Leon are believed to be the oldest living cat siblings in the UK.
The world's oldest cat ever was Crème Puff, who died in 2005 aged 38.
