This mummified cat was discovered at Tatty's tobacco manufacturers in the Minories. Traditionally, it was thought that cats warded off evil spirits. This is one of the common explanations why they are sometimes found behind walls in old houses. Another theory is that dead cats were placed there to frighten off vermin such as mice. They have even been found with a rat in their mouth. No doubt a number of cats were just walled up by accident when houses were under construction.
