Felidaedraco (female) reference summer/winter coat

This is a creature I wound up designing for . AKA mah best friend :3
She wanted a dragon-cat because she's plotting things for RP with one of her friends, The idea for the hybrid came from a story she's read at some point.
I think its for some kind of hetalia related RP? I donno. Haven't asked

Anywhoozle, I call this a "Felidaedraco" (Cat dragon). This is an ice elemental of the species, and a female example. Male's have a black sheen to their scales, and spines running along their back for threatening display. (These are warm blooded animals that lay eggs)

Habitat: Cold Climate. Most commonly found in Antartica and the North/South poles.
Can survive outside cold climates as long as there is good access to food and water. (Energy is needed to moderate temperature when outside natural habitat environment)

Abilities:
-Can change size via use of magical powers. Can be anywhere between the size of a common house cat, and a full grown tiger.
-Ice powers. This is an ice elemental beast. Can exhale an icy cold breath to freeze enemies. Can freeze surrounding environment.
-High intelligence gives these creatures the ability to speak and understand numerous languages. (Also makes them know that in-breeding is an absolute taboo)

About creature:
-Small but strong jaws. Can bite through bone and dent metal with teeth.
-Fur is thick and surprisingly soft. Changes color between the seasons.
-Eyes are hazel (Green and brown) and provide top notch eyesight.
-Ears are moderately sized but only provide okay hearing.
-Body is adorned with 36 clouded diamonds, which radiate ice energy and glow when powers are in use.
-Nose provides top notch sense of smell, and is specially designed to warm cold air to prevent frost related damage to lungs.
-Claws on front feet are retractable. 3 toes on each foot.
-Can run only in short bursts, so this creature tracks and sneaks up on prey.
-Families hunt in groups and know one another by sight, sound, and smell.
-All members of the family have their own portion of territory to guard, but all small territories make up large family turf.
-65% of the ice species if female due to cold climate effecting egg development.
-Lays 3 to 5 eggs. Parents take turns keeping an eye on them. Eggs are kept on the ground in pits.
-Hunts virtually everything in its habitat (Does not prey on humans).
