Lint and Fluff Roller.
In a house full of cats and a dog, clothes quickly get covered with various cat and dog hairs. Lazy people like me just ignore them. However, the female members of the household are much fussier :) These lint rollers are very effective at getting off animal hairs from your clothes.
They come with a roll of "sticky tape" in perforated sections. You tear off a section and wrap it around the roller. The run the roller over your clothes and the hairs will automagically stick to it. If you stick a plastic bag over the roller when you have finished, you can get multiple uses from each sticky tape.
