Ivan and Lubov Leshchenko keep the animals in the backyard of their village of Dubovy Kliuch - Oak key - in the Far East of Russia.
Close to their home was a refuge for needy animals, but it was shut in 2005. Still animals come - now the four female and six male Himalayan or Asian bears - and the couple try and care for them.
But they say it's getting harder all the time to afford the cost on their pensions.
Local radio journalists heard about their plight and tried to raise cash to help Ivan, 79, and his wife.
'Some people bring the remains of bread from a local coffee shop, but this is certainly not enough', said Lubov.
'Our problem is not solved. Now it's cold, there's a lot of snow, and we do not have time to clean it, so visitors do not come to see the bears, which means there is less food for them'. Ivan's worsening health means the bear care falls on Lubov.
Journalists from radio station Lerma in Vladivostok have taken up the couple's cause and are seeking to raise money to help the Leshchenko's feed the black bears. PIctures here and below: Yuri Smityuk
'My husband is 79 years old, he was sick for a year and cannot speak now.
'I take care of the bears by myself', Lubov said.
A local business is aiming to find a new home for the bears but so far this hasn't happened. Journalists from radio station Lemma in Vladivostok have taken up the couple's cause and are seeking to raise money to help the Leshchenko feed the black bears.
