It is not entirely uncommon for a hamster to obtain some
sort of a chronic disease that it cannot recover from. Although
of course it will be very difficult to make this decision
as the pets owner. With certain diseases this is often the
kindest and will ultimately cause your hamster the least amount
of pain. Many hamster owners take their own feelings into
account far too much when making this kind of decision. It
is most important to think about the hamster and the amount
of pain that they are in.
Never attempt to perform a euthanasia on your own. Many people
believe that they known the proper techniques and feel that
they can safely perform this at home after doing some research
on the topic. Usually this will cause your hamster more pain
than is necessary. Consequently, always seek the advice of
a veternarian first as they may even be able to offer a treatment
for the disease that your hamster is facing.
