TEN kids taken from a filthy California home with a faeces-covered bathroom had been tortured for "sadistic purposes", a prosecutor has alleged.

The children - aged 4 months to 12 years - were taken into protective custody after they were found living in squalor at the home in Fairfield, California.

They had reportedly suffered puncture wounds, burns, bruising and other injuries consistent with being shot with a pellet gun.

Cops said their parents Jonathan Allen and Ina Rogers have since been arrested and charged with neglect and torture.

The couple deny they have done anything wrong and insist they are "amazing" parents.

Deputy district attorney Sharon Henry said she was "horrified" by the kids' statements adding the torture was carried out "for sadistic purposes."

"It literally breaks your heart, and you're outraged by how a parent or anyone could commit those acts," she said.

Tattoo artist Allen, 29, the father of the children, has pleaded not guilty to seven counts of torture and nine counts of child abuse. He is being held on £3.5 m bail.

The children were taken away from their parents on March 31 after their mother reported her oldest child was missing.

Police then found the filthy conditions in the home shared by Rogers and Allen, police Lt. Greg Hurlbut said.

"Officers located unsafe and unsanitary living conditions including garbage and spoiled food on the floor, animal and human faeces.," he said.

Rogers was arrested and released after posting £7,000 bail on April 9.

The mum gave reporters a tour of her house on Monday, denying that her husband had abused the children.

She said she feels she's being judged for having so many children and choosing to home-school them.

Rogers then described herself and her husband as "amazing" parents.

She told ABC: "I strive, I thrive on being a good parent to my children.

"My husband has a lot of tattoos, he looks like a scary individual, and that's why people are so quick to judge him.

"But my husband is an amazing person. I am an amazing mother."

During the tour, the four-bedroom house, which is northeast of San Francisco, still had animal faeces in the bathroom.

Rogers said the children slept in one bedroom because they were close; cots were stored in a bedroom closet.
