Interchangeable parts and a pet

The hamsters now have a pet cat.   Fortunately it does not eat a lot, sharpen claws on furniture or make a mess.

The hamsters are also working on interchangeable parts for their transport ship.  The blueprints are drawn up before they start building.  Here is their work in progress.

Now they have a storage trunk for their ship.

 This is a mini science lab attached to the back of the ship.

 The cat is feeling left out because he can't fit on Honey's SHEV (Super Hamster Exploration Vehicle).

Here Honey is checking out his new fully-equipped SSHEV (Super Space Hamster Exploration Vehicle) before the roof is properly installed..
