My Hammys have always had a salt/mineral lick. They never took any notice but it was there if it was wanted which was never.
Anyhoo, when I got Big Pig i bought a salt lick. Again he didn't touch it. Got another when I got Little Pig, I caught him having the odd lick.
Then I read that it was un-nessacary for Pigs to have salt licks so i took them both away. Over the last few weeks Little Pig has taken to licking the palms of my hands. Does he need salt? Should I get some more licks and just leave them in there like I do for the Hammys?
