maybe it is the energy of the cat still part of it lingering on since that is the placed it died? I have recently started watching youtube clips on energy and there is this Indian spiritualist who describes the energy thing when we die the energy will slowly go away but that we leave a mark of energy living or dead, the things get energy/memory, why the clothes the person use to wear (this from India) gets burned, only the few clothes the person had on special occasions can be left to only a relative, is never given away to someone else. they do another ceremony 14 days and after some other time too after a person has departed because of the energy-thing, to send all the memory/energy where it belongs. Why they don't shake hands but say hello with their hands together, energy-space, don't want to mix up their energy with the others. Sorry! This was a long answer! hope it make somewhat sense though...:)

could explain it is energy from the cat considering it does not follow orders... ;)
