A pet shop or pet store is a retail business which sells different kinds of animals to the public. A variety of animal supplies and pet accessories are also sold in pet shops. The products sold include: food, treats, toys, collars, leashes, cat litter, cages and aquariums. Some pet stores provide engraving services for pet tags, which have the owner's contact information in case the pet gets lost.

Pet stores are extremely popular in modern society. In 2004, according to the American Pet Products Manufacturers Association, in the pet industry, live animal sales reached approximately $1.6 billion. Moreover, in a 2003 survey in the US, merely 38% of U.S. pet shops claimed that they did not sell any live animals.
