Does A Full-Grown Russian Blue Cat Shed Much?

You’ve found yourself wondering just how much your Russian Blue is going to shed. You could ask your vet, but they might be busy with other patients and unable to give you the time and attention that you deserve. 

In this case, it’s best to get some answers right away. Here are some things to keep in mind when considering the amount of shedding your cat will do:

It depends on the individual cat. Some cats shed less than others, so there’s no way of knowing what level of shedding your pet will experience without asking him or her directly (or getting him/her checked out by a vet).

There are ways you can help lessen shedding if it becomes an issue for you! For example, brushing helps remove loose hairs from the coat before they’re shed off; frequent bathing can also help reduce fur loss since water removes oil from their skin which causes dead cells from being released like dust does in humans.

What Color Are The Eyes Of A Full Grown Russian Blue Cat?

While the color of your cat’s eyes is genetically determined, it can be affected by other factors. For example, if your Russian Blue has a black or gray coat, it may appear to have a bluish tinge to its eyes. 

However, if you look closely at the pigment in the iris (colored part of the eye), you’ll notice that these cats actually have blue eyes.

In addition to fur color and lightness/darkness of fur (which can affect perceived eye color), there are other factors that can affect how light reflects off your cat’s irises:

Age: As with humans and other mammals, cats’ eyes change as they grow older. As kittens mature into adults and beyond into senior cats (10+ years old), their pupils will dilate less when exposed to bright lights such as sunlight or lamps during daylight hours–and this means that less light reflects off their retinas and into our eyes! 

This can make full-grown adult male Russian Blues appear darker than they really are because we’re not seeing all that much reflected light coming back out through their lenses anymore; however with females we should still see plenty reflecting back towards us even after reaching maturity because their pupils won’t dilate quite as much as males’ do when exposed
