* Stress: Guinea pigs are crepuscular, meaning they are most active at dawn and dusk. Showering them at night can disrupt their natural sleep cycle and cause them stress.
* Temperature: Guinea pigs are sensitive to temperature changes. A nighttime shower could make them cold, especially if the room is not well heated.
* Drying: Guinea pigs need to dry completely after a bath. This can take several hours, and they might be uncomfortable and prone to chills if they are wet overnight.
Instead of showering at night, consider these options:
* Bathe them during the day: Choose a time when your guinea pigs are awake and active.
* Use a shallow, warm bath: Fill a small container with lukewarm water (not hot!) and gently bathe your guinea pigs.
* Dry them thoroughly: Use a towel to gently dry them and a hairdryer on a low setting (make sure it's not too hot!).
* Monitor for signs of illness: If your guinea pig is shivering, lethargic, or shows any signs of being unwell after bathing, seek veterinary advice immediately.
Remember: Most guinea pigs only need to be bathed occasionally (perhaps once every few months), as they are very good at keeping themselves clean.
Always prioritize your guinea pigs' well-being and consult with a veterinarian if you have any concerns.
