FOR FURTHER INFORMATION CONTACT:  Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Pfizer, Inc., 235 East 42d St., New York, NY 
10017-5755, filed a supplement to NADA 141-152 that provides for 
topical veterinary prescription use of REVOLUTION (selamectin) in dogs 
and cats. The supplemental NADA revises the minimum age of treatment 
from 6 weeks to 8 weeks for kittens. The supplemental NADA is approved 
as of April 6, 2009, and the regulations are amended in 21 CFR 524.2098 
to reflect the approval.
    Approval of these supplemental NADAs did not require review of 
additional safety or effectiveness data or information. Therefore, a 
freedom of information summary is not required.
    The agency has determined under 21 CFR 25.33(a)(1) that this action 
is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.
    This rule does not meet the definition of ``rule'' in 5 U.S.C. 
804(3)(A) because it is a rule of ``particular applicability.'' 
Therefore, it is not subject to the congressional review requirements 
in 5 U.S.C. 801-808.
