At early morning so you can say at night
Probably at night.
Night, when they are both awake.
I don't know if it's the best but I feel most energetic and get the most work done at night. Good luck.
Rabbits are crepuscular: this means they're most energetic at dusk and dawn (and for the hours surrounding these times). Otherwise, rabbits sleep on and off all day, and they nap overnight (generally, rabbits are more active at night than during the day time).
Cover up your hamster's cage during the day and make it light during the night.
both-2 times a day
A hamster could be lazy during the day because all hamsters are nocturnal. That means they sleep during the day but are active at night.
Hamsters are nocturnal animals. This means that they sleep in the day and are awake at night. When you are awake it is the hamsters night time. Hamsters are usually most active in the evening. This is the time to play with him. Never wake the hamster up in the day time. That would be like waking a human up in the middle of the night and it may bite you.
they might simply be sick.
Hamsters are nocturnal which means they are awake at night and asleep during day. It is best to feed your hamster in the evening so that they have this food for the rest of the night when they are awake.
Check for a pulse. If its alive go to the vet.
NO hamsters are nocturnal so they sleep in the day and play in the night
