'pig' is the definition.
(I've seen this before)

'stick short rat tails on' is the wordplay.
'stick short' becomes 'glut' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tails' suggests the final letters (I've seen 'tailed' mean this).
The final letter of 'rat' is 't'.
'glut'+'t'+'on'='GLUTTON'

Can you help me to learn more?
