Any idea how old Mortimer is?

[Thrifty Hamster]

I got Mort back in April and he was a teeny little mousey who seemed like he was going to die within a couple of days due to his wound, but he cleared up real nicely within a matter of seconds of being alone and in his own place! My only question is - does anyone have any guess as to how old he is? I got him from Petco if that helps any...

When I first got him:



A Few Days Later...



I took this on August 11th.
