                  Subpart E--Identification of Animals
 
Sec. 2.50  Time and method of identification.


    (a) A class ``A'' dealer (breeder) shall identify all live dogs and 
cats on the premises as follows:
    (1) All live dogs and cats held on the premises, purchased, or 
otherwise acquired, sold or otherwise disposed of, or removed from the 
premises for delivery to a research facility or exhibitor or to another 
dealer, or for sale, through an auction sale or to any person for use as 
a pet, shall be identified by an official tag of the type described in 
Sec. 2.51 affixed to the animal's neck by means of a collar made of 
material generally considered acceptable to pet owners as a means of 
identifying their pet dogs or cats \2\, or shall be identified by a 
distinctive and legible tattoo marking acceptable to and approved by the 
Administrator.
---------------------------------------------------------------------------

    \2\ In general, well fitted collars made of leather or plastic will 
be acceptable under this provision. The use of certain types of chains 
presently used by some dealers may also be deemed acceptable. APHIS will 
determine the acceptability of a material proposed for usage as collars 
from the standpoint of humane considerations on an individual basis in 
consultation with the dealer or exhibitor involved. The use of materials 
such as wire, elastic, or sharp metal that might cause discomfort or 
injury to the dogs or cats is not acceptable.
---------------------------------------------------------------------------

    (2) Live puppies or kittens, less than 16 weeks of age, shall be 
identified by:
    (i) An official tag as described in Sec. 2.51;
    (ii) A distinctive and legible tattoo marking approved by the 
Administrator; or
    (iii) A plastic-type collar acceptable to the Administrator which 
has legibly placed thereon the information required for an official tag 
pursuant to Sec. 2.51.
    (b) A class ``B'' dealer shall identify all live dogs and cats under 
his or her control or on his or her premises as follows:
    (1) When live dogs or cats are held, purchased, or otherwise 
acquired, they shall be immediately identified:
    (i) By affixing to the animal's neck an official tag as set forth in 
Sec. 2.51 by means of a collar made of material generally acceptable to 
pet owners as a means of identifying their pet dogs or cats \3\; or
---------------------------------------------------------------------------

    \3\ See footnote 2 in Sec. 2.50(a)(1).
---------------------------------------------------------------------------

    (ii) By a distinctive and legible tattoo marking approved by the 
Administrator.
    (2) If any live dog or cat is already identified by an official tag 
or tattoo which has been applied by another dealer or exhibitor, the 
dealer or exhibitor who purchases or otherwise acquires the animal may 
continue identifying the dog or cat by the previous identification 
number, or may replace the previous tag with his own official tag or 
approved tattoo. In either case, the class B dealer or class C exhibitor 
shall correctly list all old and new official tag numbers or tattoos in 
his or her records of purchase which shall be maintained in accordance 
with Secs. 2.75 and 2.77. Any new official tag or tattoo number shall be 
used on all records of any subsequent sales by the dealer or exhibitor, 
of any dog or cat.
    (3) Live puppies or kittens less than 16 weeks of age, shall be 
identified by:
    (i) An official tag as described in Sec. 2.51;
    (ii) A distinctive and legible tattoo marking approved by the 
Administrator; or
    (iii) A plastic-type collar acceptable to the Administrator which 
has legibly placed thereon the information required for an official tag 
pursuant to Sec. 2.51.
    (4) When any dealer has made a reasonable effort to affix an 
official tag to

[[Page 32]]

a cat, as set forth in paragraphs (a) and (b) of this section, and has 
been unable to do so, or when the cat exhibits serious distress from the 
attachment of a collar and tag, the dealer shall attach the collar and 
tag to the door of the primary enclosure containing the cat and take 
measures adequate to maintain the identity of the cat in relation to the 
tag. Each primary enclosure shall contain no more than one weaned cat 
without an affixed collar and official tag, unless the cats are 
identified by a distinctive and legible tattoo or plastic-type collar 
approved by the Administrator.
    (c) A class ``C'' exhibitor shall identify all live dogs and cats 
under his or her control or on his or her premises, whether held, 
purchased, or otherwise acquired:
    (1) As set forth in paragraph (b)(1) or (b)(3) of this section, or
    (2) By identifying each dog or cat with:
    (i) An official USDA sequentially numbered tag that is kept on the 
door of the animal's cage or run;
    (ii) A record book containing each animal's tag number, a written 
description of each animal, the data required by Sec. 2.75(a), and a 
clear photograph of each animal; and
    (iii) A duplicate tag that accompanies each dog or cat whenever it 
leaves the compound or premises.
    (d) Unweaned puppies or kittens need not be individually identified 
as required by paragraphs (a) and (b) of this section while they are 
maintained as a litter with their dam in the same primary enclosure, 
provided the dam has been individually identified.
    (e)(1) All animals, except dogs and cats, delivered for 
transportation, transported, purchased, sold, or otherwise acquired or 
disposed of by any dealer or exhibitor shall be identified by the dealer 
or exhibitor at the time of delivery for transportation, purchase, sale, 
acquisition or disposal, as provided for in this paragraph and in 
records maintained as required in Secs. 2.75 and 2.77.
    (2) When one or more animals, other than dogs or cats, are confined 
in a primary enclosure, the animal(s) shall be identified by:
    (i) A label attached to the primary enclosure which shall bear a 
description of the animals in the primary enclosure, including:
    (A) The number of animals;
    (B) The species of the animals;
    (C) Any distinctive physical features of the animals; and
    (D) Any identifying marks, tattoos, or tags attached to the animals;
    (ii) Marking the primary enclosure with a painted or stenciled 
number which shall be recorded in the records of the dealer or exhibitor 
together with:
    (A) A description of the animal(s);
    (B) The species of the animal(s); and
    (C) Any distinctive physical features of the animal(s); or
    (iii) A tag or tattoo applied to each animal in the primary 
enclosure by the dealer or exhibitor which individually identifies each 
animal by description or number.
    (3) When any animal, other than a dog or cat, is not confined in a 
primary enclosure, it shall be identified on a record, as required by 
Sec. 2.75, which shall accompany the animal at the time it is delivered 
for transportation, transported, purchased, or sold, and shall be kept 
and maintained by the dealer or exhibitor as part of his or her records.
