RSA 466:13-a
The governing body of a municipality may vote to license cats in a similar manner as it
licenses dogs. If a municipality elects to license cats, the same penalties shall apply
for unlicensed cats as for unlicensed dogs, and the provisions of RSA 466:6-a and 466:8 of
the preceding subdivision shall not apply to cats. If a municipality elects to license
cats, it shall also develop a procedure similar to the procedure in RSA 466:4, III and
466:6 for group licensure. If a municipality elects to license cats, it shall require cats
to have a form of identification, including, but not limited to a tattoo, collar,
surgically implanted microchip or ear tag, or any other form approved by the commissioner
of agriculture. The commissioner of agriculture shall adopt rules, under RSA 541-A,
relative to the forms of identification.
