Quick pro/con list. I’ve owned most of these, the ones I haven’t owned I’ve dealt with and decided they weren’t for me. Regardless of the pet you choose, PLEASE research. Don’t believe the pet stores regarding cage size/type (usually too small, wrong material, or inadequate ventilation). Many of these animals require better feed then the crap at pet stores.
Hamsters
-Cheap, easy care, can (should) be kept alone. Suited to a variety of cages. Easy to feed. Quiet, unless the wheel squeaks
-nocturnal, not terribly interactive, often have bad temperaments, short life span
Rats
-AWESOME pets, like small dogs! Friendly, social, cheap.
-Need company, moderately messy, need big cage and rat-proof space for daily play. Time consuming. Should get supplemental feed (veggies, fruit, pasta, eggs, etc)
Gerbils
-Great ‘starter’ pet. Best suited for glass tank (10 gallons for 2, add 5 gallons per additional gerbil). Very clean and no smell (clean half of bedding every other week). Quiet. Cheap. Friendly if handled frequently, but equally as happy to be left alone. Very active and fun to watch. Easy to feed
-Should be kept in at least pairs. No plastic anything, or it will be chewed threw rapidly
Mice
-Cheap, clean, quiet, fun to watch. Can be friendly, but need delicate handling and will be nervous if not handled frequently. Well suited to a variety of caging. Very active!
-Females need company, males should be kept alone, but are smellier. Short lives
Chinchillas
-Active and fun to watch. Low smell, but a little messy. Absolutely adorable and can be sweet. Long lives
-Often (usually) difficult to handle, need a big cage and require quite a bit of care. Expensive initially, but fairly low upkeep costs. Need hay and sandbaths
Ferrets
- Basically a dog in a cage. HUGE personalities, very interactive. Long lives. Can be litter trained, but expect misses (poop is nasty)
-Expensive! Need regular vet care, expect big vet bills as they age. Very messy and smelly. Must commit tons of time, not ok to just leave them in the cage
Guinea pigs
-Bigger, sweet, easy to handle. Good kids pet with supervision. Very silly, and will unathletically leap in the air when excited. Slightly longer lives.
-Messy/smelly if cage isn’t cleaned enough. Need big cage (no height, but takes up lots of floor space. Need hay and supplemental veggies. Noisy, but the noises are non offensive and funny
Rabbits
-Lots of varieties, so personality will vary greatly. Even the non cuddly ones are fun pets, they like interaction and are very playful. Quiet. Can be litter trained. Low smell
-Require big cage and room to run. Destructive. Need hay. Messy. SPAY or NEUTER! Long lives.
Hedgehogs
-Exotic. Low smell. Don’t bite, fairly laid back and easy to handle
-Expensive, need a big cage. Very active (nocturnal), so better hope their wheel is well greased! Not terribly ineractive because they sleep during the day. Feeding is a big more involved
