I may be onto something......
''Kitty in My Pocket is a collection of small cat figurines that was first released in 1994 by Vivid Imaginations.[1] As well the toys being sold individually, they were sold in groups and playsets. In 2007 the line was re-released by Corinthian Marketing/MEG Toys with the same concept, but with different designs for the cats. As of 2009 the Kitty in My Pocket has been discontinued.
During the late 1990s, the line - as well as the other "in My Pocket" animals - combined with the BBC programme Animal Hospital and the animal charity RSPCA to create animals that came with "injuries" (a paint that turned red in cold water). Eventually the original "in My Pocket" lines disappeared and fully merged with the Animal Hospital brand name.
The first generation of toys were initially released in individual blind packets. Later releases came in blister packs containing multiple figures. Family group figures were also released that came with a mother, kittens and a basket. A play set was also released that consisted of a plastic house that folded out.
Two later variations on the line - Love 'n' Sparkle and Animal Hospital - returned the blind packet method of distribution as well as continuing blister pack issues.
