Didn't have a cat after the neighbours ate it - I did have design a remote control for my bed room lights - complex string based system - with enough knots you could have infinite memory.
Crystal radio was always a good start - I had a chemistry master who was a radio ham and helped me build a valve based regenerative receiver - Oooo the open topped transformer and exposed HV connections - No H&S then but I survived.
