Yes, the poem is humorous. It draws out funny situations Dad comes across with, while trying to climb a tree, to rescue a cat. Moreover, Dad' over confidence (about being able to climb the tree very easily as if it were a child' play adds humour to the poem) and the scepticism of Mum adds humour that reaches its height when at the end Dad *** stuck in the tree while the Cat jumps down safely on its own.
