.. Allergy potion - a sample of cat fur

I think Kloot is in the best position to find cat fur.

In the pawnshop. ( Check out the shelf with the blue pet carrier. )

There is some cat fur in the carrier, indeed. But the owner would want some money for it.

Although you really don't have to buy the whole carrier. You only need some fur.

Use som item on the carrier to collect the fur that is all over the carrier. That fur stuff sticks to everything.

Use the roll of tape ( There is a roll of tape in the office. ) on the pet carrier.
