Gammon is hind leg of pork after curing by dry-salting or brining.
It may or may not be smoked.
Like bacon, it needs to be cooked before it can be eaten. It may be sold on-the-bone or boned and rolled.
It may be served as a roasted joint, or as steaks or rashers.
Gammon differs from ham in that ham is cured after being cut from the carcass, and the curing process for ham may be different.
The words gammon, ham and bacon are sometimes used interchangeably.
In the US in particular, the word ‘ham’ may refer to raw, uncured hind leg of pork.(source)
So can hamsters eat gammon at all?
Yes they can nibble it.
It isn’t the best food for them, but is okay as a treat. Feed in very small amounts on an occasional basis.
Because of their dietary needs, avoid feeding them the fat.
