Why is Mrs Pumphrey worried about Tricki?
Mrs Pumphrey is worried about Tricki because he has become seriously ill and refuses to eat even his favourite dishes. He is suffering from bouts of vomiting and spends all his time lying on a rug, panting. He shows extreme lethargy and refuses to go for walks or do anything at all.
Furthermore, Tricki's physical condition is alarming. He has become hugely fat, resembling a bloated sausage with a leg at each corner. His eyes are bloodshot and rheumy, and his tongue lolled from his jaws. This sudden decline in his health leaves Mrs Pumphrey distraught with worry.
