Kids nagging for a small furry pet?

Before you commit what do you need to consider? This will depend on what animal you choose.
Hamsters – will need a very secure cage, or a habi trail to keep them secure and amused. They’re excellent Houdini artists and will escape easily if allowed. Hamsters must live alone, one per cage, if kept as pairs they will probably fight to the death of one. The cage needs wood shavings - they like to dig and keeps their coats clean. The cage must be kept out of bright light, away from draughts and heaters. Their’ teeth continually grow, so they need something hard to gnaw on. Best foods are seeds, cereals, nuts etc together with a source of protein. They are of course nocturnal, so although small, cute and furry not the best pet for a young child who will be in bed long before the hamster is awake and active. Similar sized pets to consider are mice, rats or Degus - all of which are awake during the day!
Guinea pigs can happily live inside or out providing the cage/pen is good enough, weatherproof and provides shelter from wind, rain and direct sunshine. It also needs to be predator proof with a run to play in. Indoor pets need a good size cage and access to more space where they can run around and exercise. Their diet is relatively easy, leafy green vegetables, hay, fruit and guinea pig pellets, but they can’t produce vitamin C and need a fresh supply every day. Guinea pigs are sociable animals and best kept in groups of at least two.
Rabbits also need a run to play in and a weather proof hutch to live in. They need company, either human or from other rabbits. Their diet consists of fresh hay, veg and purpose made pellets, and need to keep their teeth trim with something hard to chew. Rabbits also like to dig, so if left to run in the garden could well cause a few potholes. A cute furry animal, but possibly not one for the children to pick-up and pet. They do make excellent house pets however – the key could be in the training though!
Thought of a ferret, and why not? Not really suitable for small children, but kids from 12 years up will enjoy owning one. Ferrets live for about 10 years, so be sure first! Ferrets thrive on love and attention (don’t we all)? To live in they need to be litter trained and the house "ferret proofed". Outdoors they will need a secure hutch or enclosure. Smell can be a problem, so castration is recommended for both sexes, unless you intend breeding from them.
Other pets to consider are Chipmonks, Sugar Gliders, African Pygmy hedgehogs, but do your research first, these all need special conditions to live well and happily.
Don’t forget they will also all need Pet insurance, regular cleaning, vaccinations, grooming, exercise, food water and attention, don’t buy or adopt a pet on a whim, it for life, not just for Easter.
