Explanation : According to Wilson, “Goodwill has been
very ably divided into three types—cat, dog
and rat—in view of the peculiar habits of
these three animals. The cat tends to stick to
the abode, cat goodwill is therefore that
which will adhere to the business which is
being transferred and is the most valuable.
The dog follows his master, dog goodwill is
difficult to transfer and is correspondingly
less valuable. The rat is a migrant, rat
goodwill is practically valueless, as it
represents those customers who have no
specialities either to the business or its
properties and who may be here today and
gone tomorrow. Summed up, cat goodwill is
adherent; dog personal and rat fugitive.
Adherent goodwill is only valuable as
attaching to the business; personal goodwill
is unsaleable, fugitive goodwill is only
valuable in that as one fugitive goes another
may arrive.”
