Pet owners who have cared for small pets in the rodent or reptile family may wonder what budgies should smell like, considering other small pets can have such a strong odor. Budgies are a totally different ball game, not only do they have a particularly lackluster sense of smell, but they don’t produce odor themselves. Under good conditions, what budgies smell like is nothing, what they rub their heads on, or what they eat.
This extends to their poop as well, if your budgie’s poop is smelly then he may be ill and you should seek veterinary care. Literally, you should be able to not clean your cage(s) for weeks (totally not recommended) and it should not smell. If it does smell and you have been feeding fruits and vegetables look to see if you’ve missed some scraps of food that are rotting. Also, watch out for ants!
Typically, I find that my parakeets smell like very mild citrus, which is pleasant and comes from their seed mix. For a while I was freaked out because Toby smelled like tomato soup, at the time I was trying her on Roudybush Pellets and it turns out those smell like tomato soup to me.
Another cause of transient smell can be eating fresh vegetables and fruits. After Kelly eats broccoli she has very distinct and fairly gross broccoli breath. That makes sense because the broccoli is hanging out in her crop for a while with her hulled seeds, basically composting itself. If that smell persisted it would be another sign of illness such as a crop infection, impaction, or sour crop.
Persistent bad breath can be a sign of other internal issues as well. If your budgie has a foul odor coming out of its mouth that can’t be tied to eating something and lingers beyond a day then it is probably time to find an avian vet and get a diagnosis and treatment.
For anyone who’s been wary of getting a budgie due to the potential of bad odors, fear not! Their lack of smell is part of what makes a budgie an excellent pet for a smaller space/apartment, in my opinion. And for those of us who are already budgie owners, keep your nose at semi-alert, a new odor on or around your budgie can be an excellent first warning of illness or habitat conditions like rotting food that need to be remedied.
