How long should it take for allergy symptoms to show after exposure to cat?

by Symptom Advice on July 25, 2011

Please help.. I don;t thnik it is a cat allergy cause it takes time for me to experience it.

Usually immediately. sometimes it takes just walking into a room with a cat and sometimes it takes touching your eyes/nose after touching cat.

sometimes it takes me a few hours before the symptoms show…

3-5 min. or depending how allergic and how serious ur body is. 1-2 min.

Usually the alergies will happen immediately, like sneezing or rashes, but sometimes they wont start for a while. Depends on how you were exposed, and how much you are allergic you are to cats.

Either immediately, or, after a few hours. I get allergies if I stay over a friend's house who has a long-haired kind of cat.

My daughter used to be able to play with cats and then around
the age of 8 (I think) she started itching after playing with them.
Now she is 11 and if she touches them she has to wash her
hands immediately or her nose starts to get all congested
and she gets itchy.

Depends on the level of your allergy to them. to some people is is immediately and others it takes some longer time.
