This is a cleaned up model from a scan by chdiago at www.123dapp.com.
Printer Brand:
Ultimaker
Printer:
Ultimaker Original
Rafts:
No
Supports:
Yes
Resolution:
0.15 mm or better

Notes:
Print standing up with supports. The tail is the only tricky part, so you might want to use a brim to make sure the support for the tail is secure during printing.
I used Meshmixer to clean up the raw 123D Catch scan and to do some sculpting.
