Writer Carla Lane is launching an appeal to help save the animal welfare centre she runs from the threat of closure.
Carla Lane says the animal centre mean she has no time for writing
The Animaline centre in West Sussex costs about £250,000-a-year to maintain which Ms Lane has largely funding through her own money.
But she says the centre is taking up so much of her time she can no longer write enough to bring in the funds to run the centre.
The writer, famous for creating BBC sitcoms like Butterflies and Bread, started up the charity Animaline in 1987 and the centre near Haywards Heath opened in 1993.
It cares for sick, abandoned and rescued animals, birds and reptiles, before finding them homes or releasing them back into the wild, with the numbers dealt with since 1993 stretching into the thousands.
They have ranged from elderly horses to injured Trafalgar Square pigeons to abandoned cattle.

In March this year Ms Lane published a book of poems with all the proceeds going to the charity.
She hopes the Animaline Appeal 2003 will raise £500,000 - enough to keep the centre open for the next two years, and then keep bringing in enough to keep it in business.
At the centre of the appeal will be the release of a fundraising CD single by local singer-songwriter Ashley Bruce.
They struck up a friendship after Mr Bruce had a brain haemorrhage four years ago at the age of 27 and Ms Lane, who had heard of his situation through the media, helped him with his fight back to fitness.
