I think the song is about being unwanted, hence the semantics of the song: Spot, spider, pimpels, very smelly etc. and the line about being un-loved. And the title, RATS, obviously - the definition of something not wanted.
Otherwise just a lot of funny Syd moments here, his lines full of assonance, fun words, stream of consciousness - it's all there, but with the departure in the subject of something not welcome.
