Sometimes hamsters can get the first signs of cataracts before they are two years old, and have eye problems. Hamster breeders try as hard as they can to breed healthy hamsters with no history of cataracts.

However, it is a bit more difficult because cataracts usually appear when the hamster starts to age.

That’s why breeders avoid keeping old hamsters that have cataracts, in order to reduce the chances of breeding and giving birth to hamsters with genetically impaired eye health or cataracts.

Injuries can cause cataracts in hamsters

Sometimes awkward injuries to the area of ​​the eye or the lens of the eye in hamsters can cause cataracts.

Most often, this happens with aggressive hamsters who fight too much and hit an object, which eventually ends with the appearance of cataracts, this is especially true for Syrian hamsters.
