Need help with skin care?

Since early December I have been breaking out randomly with little itchy bumps. They itch for a few days then slowly disappear. They happen in random spots on my stomach, back arms and legs. I have not added any new cleaning/health care products to my home. The only things new to my home is a kitten, however she was in the home for about 2 weeks before I started breaking out and I have never been allergic to cats in the past. The second item new to my home is my dog had some puppies, but I am not allergic to dogs either. I thought about bed bugs but it is only affecting me and my husband sleeps right next to me every night. It isn't contagious as none of my 4 children or my husband has had any skin issues. I was wondering if anyone here might know what is going on. I have a doctors appointment set for next week but this is driving me crazy. I try not to scratch but the itching becomes unbearable at times.
