Leaking Water Bottle

Leaking water bottles is one of the most common problems faced by most Hamster owners.

There are three major causes that can lead to leak in your Hamster’s water bottle. The causes are as follows:

  • No vacuum can lead to leaking water bottles. You have to be very careful while picking up the bottle for your Hamster. Some brands of bottles do not provide a gasket, which is important to sustain a vacuum.
  • Sometimes a bottle also leaks due to improper maintenance. You should clean the bottle properly. If the food particles are stuck in the nozzle, the bottle can leak.
  • In some cases, your Hamster might be the cause of leaking water bottles. Some Hamsters tend to chew their water bottle’s nozzle, which can lead to the water leaking.

Frozen Water Bottle

During winter, many Hamster owners face the problem of frozen water bottle. Water in our Hamster’s water bottle will mostly freeze in sub-zero temperatures. This in turn can lead to dehydration in Hamsters.

Frozen water can also lead to cracking of the bottle. If your Hamster uses a bottle to drink water, it is advised to arrange a thermal case for them.

It is best to use a dish or bowl to serve water to your Hamsters in winters. Vessels with deep sides help to prevent water from freezing.
