Is it common that my cat gets a head cold when seasons change?
Pure bred Siberian forest cat 18lb mucsle can break bat on his chest!
I sent questions about allergies and my cat but picture didn't go through here it is. Meg is my name. My Siberian is Merlin.
Cats getting head colds during season changes isn't common if its an indoor cat. However, outdoor cats exposed to cold weather are more susceptible.
In this case provide a warm bed and extra protein in their diet when they return home. Cats can get frostbite and hypothermia just like humans do. The extra protein will help thicken the fur adding a little more insolation. Adding a fatty acid supplement such as fish oil will also help their coat.
You also mentioned allergies but didn't elaborate so here is the link to allergies in cats.
