No full-service shelter or other shelter for homeless animals required to have a permit issued pursuant to subdivision (b) of section 161.09 of the New York city health code shall release a dog or cat to a person claiming ownership thereof, or to a person adopting such dog or cat, unless such dog or cat has been sterilized by a licensed veterinarian; provided, however, that such requirement shall not apply: (1) if a licensed veterinarian certifies to such shelter that he or she has examined such dog or cat and found that because of a medical reason, the life of such dog or cat would be endangered by sterilization; provided, however, that such reason shall not consist solely of the youth of such dog or cat, if such dog or cat is at least eight weeks of age.

Chap. 8, Sec. 17-804 (4) b. No pet shop shall release to a consumer a dog or cat that has not been sterilized by a licensed veterinarian; provided, however, that such requirement shall not apply to a consumer who presents to the pet shop a letter from such consumer’s licensed veterinarian, dated within the immediately preceding ten days, stating the reason(s) why, in the opinion of such veterinarian, such dog or cat should not be sterilized until a later specific date, not to exceed four months following the date of such letter. Such letter shall state that such veterinarian will cause such dog or cat to be sterilized at the request of such consumer on or before such later specified date. Such veterinarian shall also provide to the pet shop a certificate, in such form and manner as determined by rules promulgated by the department, stating the date on which such sterilization was performed.
