Our djungarian hamster is apparently getting hot when temperatures reach about 25°C. She then sleeps outside her house, in a corner of her terrarium, leaning on the glass and looking annoyed. She also tried to dig deep, probably an instinct to make a hole deep enough to get into colder regions of soil.

As the weather will get even hotter during the summer and we don't have airconditioning, what could we do to make the hamster feel better? Would it help to add some small fan (like a computer cooling fan) to circulate air in the terrarium? Or add some rocks or other objects outside and inside her house with higher thermal conductivity so that she could cool herself down by leaning on them?

Enclosure Type

Air circulation is very beneficial to any animal, having an enclosure that can provide this will help with air quality and temperature. Glass terrariums do not provide adequate air circulation and tend to retain heat.

Cooling Options

1) Granite stone plaque - stone is generally cool, it's not a long term solution but will help.

2) Keep cage out of direct sunlight.

3) Use black out blinds to prevent the sun from warming up the room.

4) Purchase a portable air conditioner.

  • We already have the terrarium in a darker, cooler room, so options 2 and 3 are already implemented. Could a hamster suffer from too much draft, if I add a small fan to exchange the air inside. – Petr Pudlák May 11 '18 at 9:13
