Turning into Zombie

’twas not the cat sat on my mat
but a grizzled three toe’d sloth.
I looked at him and him at me and
on the spot we did agree,
to chat a while while having tea,and very soon or sooner still I realised the sloth was ill,what could I do but call the zoo,we both bet they’d call the vet,of course we both were right and as night fell with some slight attention from said vet the sloth got very well,then after chatting for some more he took position by the door and left the mat for my black cat which was surprised to find a sloth sat by the door,in fact nothing could surprise him more,’cept if I called him Rumplezub which is not his name at all.
