No, that is *not* a legal deduction on your tax return.
I seem to have been adopted by Phineas. So now I have two cats in my life, Goliath and Phineas. Phineas still has a recurring sneeze, which is a wee bit disturbing. He's been to the vet twice for antibiotics and has had a steroid shot as well. He and Grady, the feral cousins to Ferb, Doodledorf, and Ozzie, have had the most trouble kicking the infection. So something in their makeup is different.
In general, Phineas likes to be where I am, if only to sleep. At times he's also hyper-alert. He has a fascination with computer cursors and computers in general. So if your tax return is a wee bit delayed this year, it's because he's having trouble learning to ten-key with those paws. Or because he's interfering with the process in general and deciding what is and what isn't a legitimate business deduction.
Thank goodness the desktop is only used for blip, twitter, the occasional spreadsheet, and transmittal letters. I can tolerate a desk cat most of the time, though my office is still in cleanup mode.
