Cats can see some colors and can tell the difference between red, blue and yellow lights, as well as between red and green lights. [5] Cats are able to distinguish between blues and violets better than between colors near the red end of the spectrum, but cats cannot see the same richness of hues and saturation of colors that humans can.

For example, if wearing an earplug with a NRR of 25 dB and an earmuff with an NRR of 20 dB, the combined protection would not be 45 dB. Instead, 5 dB should be added to the higher of the two NRRs. [26] In the preceding example, the combined earmuff and earplug NRR would be estimated at 30 dB (25 dB plus 5).
Pre-molded earplugs have a preformed shape and a push-to-fit design. Formable earplugs are pliable and take the form of an individual's ear canal. Roll-down foam earplugs are one of the most commonly used earplugs, and are made from slow recovery foam which expands after it has been "rolled-down" and inserted in the ear canal, creating a ...
The good news is, cats can absolutely see color, which will come as a relief if you've spent money investing in a range of the best interactive cat toys in bright and bold hues! However, while ...
Using both ear muffs (whether passive or active) and earplugs simultaneously results in maximum protection, but the efficacy of such combined protection relative to preventing permanent ear damage is inconclusive, with evidence indicating that a combined noise reduction ratio (NRR) of only 36 dB (C-weighted) is the maximum possible using ear ...
Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
Keratoglobus (from Greek: kerato-horn, cornea; and Latin: globus round) is a degenerative non-inflammatory disorder of the eye in which structural changes within the cornea cause it to become extremely thin and change to a more globular shape than its normal gradual curve. It causes corneal thinning, primarily at the margins, resulting in a ...
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins.
