The mother of a woman who killed herself while she was in prison has said mentally ill people should not be assessed in prison.
Sarah Reed, 32, died in Holloway Prison, north London in February last year.
She was waiting to be assessed to see if she was mentally fit to plead after being charged with assaulting a nurse in a secure psychiatric unit.
The government said it took prisoners' mental health "extremely seriously".
Sarah's mother Marilyn Reed said if people had done their jobs properly, she would still be alive.
The jury at Sarah Reed's inquest recently concluded a narrative verdict.
It found that a series of failures such as not treating her in a timely manner, mismanagement of her care and monitoring, plus an unacceptable number of cancelled visits by staff all significantly contributed to her deterioration.
Ms Reed was waiting in prison for nine weeks for an assessment.
'No food or water'
Her mother said: "It needs to stop, it needs to be investigated. We need to have things put in place that the mental health are dealt with in medical places. There's no excuse and I want this to change, that no other family is torn apart or devastated."
"If they'd have said a secure unit, hospital, whatever, I'd have said fair enough. But prison? Remember she hadn't been found guilty of anything, she'd been accused of a crime, she hadn't been sentenced, yet she was placed in Holloway," she added.
She said the inquest was painful for her and the family.
"The revelations such as her not being allowed to have baths or showers or being able to have food or water because they felt she was in such a psychotic state that she couldn't be approached.
We thought that if she'd been a dog or a cat, kept under those conditions, someone would have been charged for animal cruelty."
She said her daughter had a history of mental health problems, which stemmed from her not recovering from the death of her baby daughter in 2003.
Last year 22 women died in prison. Holloway, which was western Europe's biggest female-only prison, was closed last May after it was branded inadequate by then Justice Secretary Michael Gove.
In a statement, the government said: "We take the mental health of prisoners extremely seriously and are increasing the support available to vulnerable offenders.
"We are putting more funding into prison safety and have launched a suicide and self-harm reduction project to address the increase in self-inflicted deaths and self-harm in our prisons."
Correction 22 August 2017: This page has been amended to clarify that it was Michael Gove who described the prison as inadequate.
