What pets would be suitable for someone who lives in a small apartment without a yard?

There are several pets that would be suitable for someone who lives in a small apartment without a yard. Here are a few options:

1. Small mammals: Small mammals such as hamsters, gerbils, guinea pigs, and rabbits can make great pets for people with limited space. They can live comfortably in a cage or enclosure, and while they do need exercise, they can usually get enough by playing in a designated area within the apartment.

2. Cats: Cats are another good option for apartment dwellers. They tend to be fairly low-maintenance, and most are happy to live an indoor life. They do need some space to play and climb, so make sure you have some vertical space and hiding spots for them to explore in your apartment.

3. Fish: Fish can make great pets for people who don't have a lot of space. A small tank or aquarium can fit nicely on a countertop or shelf, and watching the fish swim can be a calming and enjoyable activity. Just be sure to research the specific needs of the species of fish you want to keep, as they can vary widely.

4. Birds: Small birds such as canaries or parakeets can also make good pets for apartment dwellers. They don't require a lot of space and can be kept in a cage. Just be aware that they can be quite vocal, so you may want to consider how that will impact your living situation.

Overall, the key to finding a suitable pet for a small apartment is to choose one that doesn't require a lot of space, is comfortable living indoors, and fits your lifestyle and personality.
