carpets I'd steam clean if possible (or hire a rug doctor thing, they do pet friendly shampoos). If not I'd be tempted to dilute white vinegar and spritz the whole carpet, put some baking powder down and then hoover
Plastic toys, I'd stick in the bath. I use bleach or milton on all things for my pair but thats because of the EC not neutralising. White vinegar should work fine.
Wooden toys I threw away as I couldn't clean them properly and all fabric went in a hot wash
as for furniture I'd wipe it down with vinegar solution
