I might depending on the pet and length of their trip. :)

Would you buy lunch for a friend?

We did do that a few years ago when he was on strike and they were hurting a bit.

Would you ever intentionally hurt yourself?

Only to protect a member of my family or a close friend. Not normally.

Would you take a bus on a trip?

I think so, although I would tend to try and avoid something cruel.

Would you ever not answer rather than hurt someone?

No.

Would you ever clean up someone else's mess?

emotional or literal?

would you ever housesit for your neighbours?

No.

Would you ever pick up and throw away junk left on the ground at a park?

I must admit, I've kicked my cat before -- but only for an egregious offense. I would never do it hard (only to demonstrate an issue) and I would never do it again.

What is the longest distance you have ever driven in a car, and why did you go?
