Why am I allergic to cats?<|im_end|>
<|im_start|>assistant
Allergies to cats are primarily caused by a single protein which is found on the skin and in the saliva. There are at least seven other cat proteins that may cause cat allergies in humans. A combination of these allergy producing proteins accumulate on the fur and skin of the cat during grooming.<|im_end|>
