The topic sentence of a paragraph is typically found at

paragraph is the first paragraph.  It makes the claim that foxes and cats are
similar.

In order to support this, the author gives us a
number of statements that tend to prove that foxes behave in ways similar to how cats
behave.  Essentially all of the other sentences in the paragraph support this idea.  You
can simply list the other ideas given in the paragraph.  Among these
are

• Both cats and foxes threaten in the same

• Many of their vocalizations are the

• They hunt in similar
  ways.

If you want, you can list the exact ways
in which these are true.  At that point, you will have identified the topic sentence and
the supporting facts.
