Horrified mum Tiffany Senara has told how she found 28 dead guinea pigs wrapped in puppy pads and buried in shallow graves - in her back garden.
The 22-year-old made the grim discovery after moving into her new Abbey Hulton council house.
It has emerged Tiffany is living in the same Blakelow Road property where the RSPCA last year found 42 dead guinea pigs.
It is the latest blow for Tiffany who had previously complained to the council about her back garden being covered in broken glass and rubble.
The mother-of-two said: "I was raking my back garden when I came across a shallow grave. I kept searching and have dug up 28 guinea pigs.
"The first time I pulled out a puppy pad and the smell was horrendous. I&apos;m surprised the whole of Abbey Hulton couldn&apos;t smell it. I&apos;ve stopped working on my garden now because I am dreading finding anymore.
"The RSPCA has told me that because it has already prosecuted a person over this case there is nothing else they can do."
North Staffordshire Justice Centre last year heard how more than 130 animals - including cats, dogs, rabbits and guinea pigs - were found at the Blakelow Road council house after neighbours complained about smells coming from the property. The entire house was covered in animal faeces and infested with rats.
A woman living at the property was handed a lifetime animal ban by magistrates. Her teenage daughter received a five-year animal ban.
Following the discovery of more dead guinea pigs, an RSPCA spokesman said: "Unfortunately we are unable to discuss complaints about specific people and what action may have been taken. We understand how frustrating this is for animal lovers but releasing information could prejudice a future prosecution or could lead to us being fined.
Stoke-on-Trent City Council has removed the dead bodies from Tiffany&apos;s garden.
