In its monthly message the branch is urging people to consider adopting one of its cats looking for forever homes.
"Diane is a 12-month-old tortoiseshell female rescued from a hoarder situation," said Anne Wignall, trustee of RSPCA Shropshire branch.
"She is a little shy and hissy on first meeting and so will benefit from a peaceful situation. However, she could possibly be homed with other cats, maybe older children, and could go outside eventually.
"Meanwhile Duane is only six months old and is very quiet and shy, a stray from a colony of five cats.
"He will thrive as an indoor cat in a quiet household, perhaps with older children but definitely not with dogs."
Gizmo is a four-year-old black and white tuxedo.
"He is a lovely, friendly outgoing boy, who is very chatty and could live with teenage children. He is a great cat with ‘catitude’," said Anne.
Anyone wishing to meet the cats should contact the RSPCA Shropshire branch at: email@example.com or 07703 567 935.
