Some pets can be expensive. The larger the pet, the more food it will probably eat and some pets also require visits to a veterinarian for shots. Other pets need equipment such as an aquarium, cage or hutch. While dogs can be very responsive to humans, they also require a lot of attention and care. Birds can be enjoyable but can not tolerate much handling.
Fish can be fun to watch but tend to die easily which can create an awkward situation.
Hamsters are basically nocturnal so they will usually be active at night while your child is asleep. If you do decide to get a pet and it is one that your child will come into physical contact with, teach your child how to treat the animal to avoid scratches or bites. You should also be aware that children with asthma or allergies may not respond well to some animals such as cats - but an alternative pet can often be found. Pets can be very enjoyable for the entire family. Before getting one though, make sure you have considered the consequences of bringing one into your home.
