Do you have a kong you can fill with peanut butter and then freeze it? This will give them something to do for a while so that you can get some things done.
While, I love my animals, I sometimes have the same feeling. Both my dog and cat are very needy, and at times I just need to get something done!
This is where the kong or other toys (nina ottosson, hide a squirrel, etc) they can play with themself come in handy.
Another idea would be to just play with them for a while and tire them out and then hopefully you'll get your me time.
