Cats and Dogs Are Not Colorblind
So, technically dogs and cats cannot see as many colors as human beings. However, it has been proven that dogs and cats can see both greens and blues. They also have more rods in their eyes than humans do, meaning that they can see better than humans in low-light situations.
Space Isn't Exactly 'Cold'
The void of space can actually be a multitude of temperatures all at the same time. For instance, just outside of the Earth's atmosphere, space is roughly 250 degrees Fahrenheit. Whereas, the coldest corner of space sits around -454 degrees Fahrenheit. It all depends on your location in space, which we hope isn't too far away from the Earth.
