Most of us have seen a cat’s eyes shining at us in the dark as we drive by. The cat’s eyes themselves do not glow. The glow is only a reflection of the cat’s headlights.
A cat has an extra mirror like material in the back part of its eyes. This special material reflects direct light and causes the cat’s eyes to “glow” brightly.
A cat’s eyes have slit like pupils. In bright light the pupils become narrow slits that shut out much of the glare.
At night they widen to great circles to let in all the light there is. But even a cat cannot see in total darkness, as some people think.
Many animals active at night, such as deer and raccoons, have this mirror like material in their eyes, too. – Dick Rogers

what does the baby bat do while the mother hunts for food? does he hang out in the cave alone? or does the bats carry the baby with then when they leave the cave in some sort of pouch or just by hanging on to her. With bats being mammals they do nurse their young, don’t they? Just curious. Thanks for your time.

Hi Marsha. I am Pari. Thank you for your comment. As we all know not only with human that mother nurse their young but also with animals. But as far as I know, only few animals carry their baby where ever they go like kangaroo. But with bats, when ever the mother bat hunts for their food, they leave their young in the cave where they stayed. Baby bats just stayed there or just flying around while waiting for their mother. Thank you again Marsha for commenting on my blog. I really appreciate it. Hope that you continue commenting on my blog.

I’m new to developing sites and I was wondering if having your site title relevant to your articles and other content really that important? I notice your title, “Why do cat’s eyes glow in the dark? Natural World of Living Things ” does seem to be spot on with what your blog is about yet, I prefer to keep my title less content descriptive and based more around site branding. Would you think this is a good idea or bad idea? Any kind of assistance would be greatly valued.

I have got one recommendation for your webpage. It seems like at this time there are a handful of cascading stylesheet issues when launching a selection of webpages inside google chrome as well as safari. It is operating alright in internet explorer. Perhaps you can double check this.
