Give me a list of pets that require low maintenance.

Owning a pet indeed requires certain energy and commitment. Following is a list of pets that have low maintenance based for experiences from various owners.

- Goldfish or other similar size fishes.
- Hamsters
- Guinea pigs
- Birds
- Cats. Contrary to popular belief, cats are very self-sufficient pets. If proper food is on their plate and a favourite resting place, one doesn't generally feel their presence. However, they are hard to ignore.
