Why after a cat scatches you the spot gets swollen and itchy?
2 doctors weighed in across 2 answers
Infection/irritation: This is very likely superficial infection or could represent a true mild allergic response. The allergists might call this a scratch test. Cats carry a lot of bacteria that can get out of hand quickly. Cat bites should generally be treated with antibiotics early.

Histamine: Breaking the skin releases histamine which makes holes in the blood vessels to allow immune cells to go to the scratch. These immune cells fight the germs from the cat scratch. By the way, cat scratches can be truly nasty things with super bad infections. Be careful and watch for red streaks, hot, painful, swollen area.
