Is this normal, or should I worry? The behaviours that scare new keepers, explained.
5 questions, answered honestly and judgment-free.
A lot of “weird” small-pet behaviour is normal: rabbits flopping over, guinea pigs popcorning, rats bruxing (tooth-grinding) when content, hedgehogs self-anointing, ferrets doing the “weasel war dance,” and nocturnal pets sleeping all day. It becomes a worry when behaviour pairs with a red flag — not eating, a hunched posture, laboured breathing, or a sudden change. When unsure, watch closely and compare to the species guide.
Usually fear, not aggression. A prey animal that’s newly homed, startled, woken (hamsters especially), or handled too fast will nip to say “back off.” Build trust slowly with food and calm, low handling, don’t grab from above, and let them come to you. Sudden new biting in a previously friendly pet can signal pain — worth a vet check.
Look for relaxed, playful body language: rabbits “binky” (leap and twist) and flop on their side; guinea pigs popcorn and wheek for food; rats brux and “boggle” when content; a happy ferret does the war dance. A confident pet that eats well, explores, grooms and rests in the open is a good sign.
Usually yes. Hamsters, mice, chinchillas and sugar gliders are nocturnal, and rabbits are crepuscular (most active at dawn and dusk), so daytime quiet and night-time activity is normal. Interact in the evening when they naturally wake, rather than disturbing a sleeping animal. Degus are the exception — they’re diurnal and active by day.
Almost always normal. A newly-homed prey animal needs days (sometimes weeks) to feel safe, and hiding is how it copes. Give it quiet, plenty of hiding spots, and time; win trust with food rather than forcing interaction. Worry only if it’s also not eating or drinking, or looks unwell.
