Pet stores commonly sell fish for home aquariums, small birds such as parakeets, small mammals such as fancy rats and hamsters, and small reptiles such as lizards and snakes. Mice, goldfish, and other animals used as live food (called feeders) for reptiles and fish are also usually sold.
Less common in pet stores are larger mammals such as dogs and cats. In the UK and many other countries, dogs and cats are not sold at pet stores.
A leash or a lead or lead line is a rope or similar material attached to the neck or head of an animal for restraint or control. On the animal, some leashes clip or tie to a collar, harness, or halter, while others go directly around the animal's neck.
Exotic pets such as sugar gliders, large snakes and large parrots are available at some pet shops. Because the care of these types of animals is difficult and expensive, these are most often carried only in stores that specialize in exotic animals.
The definition is an evolving one; some rodents, reptiles, and amphibians have become firmly enough established in the world of animal fancy to no longer be considered exotic. Sometimes any unique or wild-looking pet (including common domestic animals such as the ferret and the domestic rat) is called an exotic pet. "Exotic" may also be used for a species which is non-indigenous to the owner's locale.
Many major pet stores and service providers (such as veterinary insurance carriers or online retailers) tend to classify any animal besides cats, dogs, or fish as "exotic".
