Hamsters – Average Lifespan: 4 Years

The Hamsters again are very common pets with kids the world around even though they too, like the Rabbit, have an extremely short lifespan. Averaging anywhere between 2 – 4 years the Hamsters make up for this short lifespan in the same way as Rabbits, excessive breeding. Hamsters can reach sexual maturity as young as 1 month old and can give birth multiple times a year, each time possibly bearing multiple young.
