This excerpt could be considered humorous because of the way in which the events are retell and because of the choice of words. their arrival is portrayed in such a way that the reader might think, it could have a deeper meaning. For example
"<span>It regarded us a while without curiosity but with caution, and after we were seen to be harmless" This might be understood as a fun way of expressing that people were all over them, to check who they were, they pay close attention to these "new people" until they were convinced they are fine. </span>
Cats sleep, anywhere,
Any table, any chair
Top of piano, window-ledge,
In the middle, on the edge,
Open drawer, empty shoe,
Anybody's lap will do,
Fitted in a cardboard box,
In the cupboard, with your frocks-
Anywhere! They don't care!
<span>Cats sleep anywhere.</span>
