First, do hamsters blink? I know they have eyelids because my hamster obviously closes them when he sleeps, but I’ll be damned if I’ve ever seen him blink in his day-to-day activities. It kinda freaks me out.
Second, every few days, my hamster’s balls descend out of his body, he drags them around for a day or two, and then – sloop-- they get sucked back in. Why do they keep shifting positions? Do male hamsters go through a kind of “heat” period, similar to females? (And I gotta say, if my ball-size-to-body-size ratio was the same as his, I wouldn’t be able to wear pants.)
And finally…hmmm, I can’t think of my third question right now. If it comes to me, I’ll post it later.
Hamsters blink one eye at a time. Perhaps your hamster is always facing the same direction, so you never see him blink.
At low temperatures, the testicles may retract (George from Seinfeld called this Shrinkage).
I love hamsters, had 3 of them, Tarzan, MacGregor and MG. Tarzan lived the longest, about 4 years. He had the run of the house and only returned to his cage to eat or poop. Most mornings I’d find him cuddled up in bed with me. He accompanied me to school each day in 7th,8th and 9th grade. I had a zip-front sweatshirt with a drawstring at the bottom. He spent his days inside my sweatshirt or riding on my shoulder.
If there’s anything credible to find on the net about hamsters blinking one eye at a time, then it’s drowned by “did you know” and “useless trivia” sites, most of which would make Cecil cry. I smell an urban legend.
And as far as the testicles and warm weather, as a male, I’m painfully aware of this unfortunate occurance. However in the case of my hamster, it’s usually the same temperature in his cage (it being summer, I imagine it never really cools down to the point of testicle shrinkage), so I don’t think that’s it.
Plus his head is small enough to where I can usually see both sides of it at the same time, and still I see no blinking. I’ve been watching him a lot lately to catch a blink, but he just doesn’t do it.
