8 day rental from Budget pickup at hollywood CA, drop off at Cambridge MA $726 without damage waivers or any special road side asst, etc.
3000 mi. at 30 mpg = 100 gal of gas. Average
Cost per gal = 3.30. Total fuel bill = $330.
A little over $1050 vehicle costs.
If you can put the hammer down, you can definitely get there in less than 8 days, 6 or less if you're experienced, it's 60 hrs. of drive time. Figure in a motel stay at $100/night twice or three nights, the balance catching a long nap in the car (choose those seats wisely) and your trip costs less food and drink is still under $1500.
I haven't talked to your cat but I would think 4 or 5 hrs. in a carrier on an airplane is going to be less stressful than a few days long trip on the road.
