Why Do Rats Have Red Eyes

Rats have red eyes for a variety of reasons. Some of these reasons are due to their environment while others are due to their genetics.

One reason why rats may have red eyes is due to their environment. If a rat is living in an area with high humidity their eyes may become red and irritated. This is because the humidity can cause the blood vessels in the eyes to expand which gives the eyes a red appearance. Additionally if a rat is living in an area with a lot of dust or pollen their eyes may also become red and irritated. This is because the dust and pollen can irritate the eyes and cause the blood vessels to expand.

Another reason why rats may have red eyes is due to their genetics. Some rats are born with red eyes and this is a result of their genes. Additionally some rats may develop red eyes as they age. This is because the blood vessels in the eyes may become more fragile and break more easily.

If a rat has red eyes it is important to take them to the vet to ensure that there is no underlying medical condition causing the red eyes. Additionally if the environment is the cause of the red eyes the rat should be moved to a more humid or dust-free area.
