So dkitty is 15. Has always sooked into, slept with and gravitated towards ds1. Ds2 is 8, and autistic (relevant in that he doesn't have a natural affinity towards animals and tolerates the cats and dogs in the house but no interaction.). Since ds1 moved out dkitty has began to sleep in ds2 bed near the top, and ds2 has quite enjoyed it and will pet dkitty. Ds2 face has broken out in a horrid rash. Is it possible for this to be a cat allergy that has only become noticeable since ds2 has started to come into close contact with dkitty? We have had cats and dogs since ds was born so this is not a new cat into the house.
