Wow, it sure sounds like the three of you were bitten by a spider or something. They can be terribly painful. I'm so glad that Flutter is beginning to feel better and hope that you will be on the mend soon too. Maybe there is a non-chemical way you could de-bug your house without endangering your furries.
I made the mistake of having a pest control person come to our house a month and half ago to spray for carpenter ants. I really really didn't want to do it but we had to because we are putting our house on the market and we had to resolve the problem. We took all the animals out of the house for the day and then we all went back in that night. The cats all seemed okay (I washed all their bedding and put every catfood dish and water dish through the dishwasher etc..) but every muscle in my body was sore the next day and I could barely move. I won't ever use pesticide again.
