What is best?

Hi all

Hope you can help. My little cat oliver is 2 years old, and totally adored
and spoilt. The thing is, I hate going away and leaving him, as the people
who look after him only pop in to feed him and let him in/out. It's kind of
them to do so, but on the rare occasion if I do do go away, all I do is
worry constantly about him, and whether he's lonely, which is why I do so
very rarely. To be fair, he seems fine when I get home, allbeit a little
clingy for a few hours , but my question is, what is best for him, that he's
on his own territory but very lonely, or that I give him one of those pills
to make him drowsy then take him with me on a 3 hour drive to my parents,
where he will be with me, but cooped up in a (spacious) strange environment
for a week?

Any advice appreciated
Many thanks
Lisa
