The first products will launch in January 2012 and roll out over the following few months.
The company is hoping to secure listings in DIY sheds, garden cenrtes, pet retailers and RSPCA centres.
"Sert-MST has agreed to work with the Society to ensure all the products listed on this and any future licence agreement are manufactured for animal-loving consumers who really care about the welfare of animals, whether farmed, wild or domestic pets," said RSPCA trading director Cathy Snow.
"We believe this will give the products a unique selling point. In addition, every product sold will be supporting the work of the RSPCA and helping us care for the animals in our many centres throughout England and Wales."
