Oh dear.  I wish I could offer advice but Persia never goes on the OUT
unless I pick her up and put her in her kitty-walk on the patio.  I know
there is a way to attach this sort of device to a cat door but given your
entry-way that wouldn't be practical, would it?  Purrs that Abelard comes
home and stays there!

I am so sorry, Pat.  Purring for him to get his butt home.

All that I can suggest is keeping him inside, and hiring a pet
behaviorist.  Maybe your vet can suggest some drug that will help but
this sounds like a behavior issue. Also didn't this just start when a
new kitten was brought home?  Good luck

Is he neutered?    He probably has adopted another home.  Does he appear
well fed?  MLB

That's really weird, since it's a new behavior. I wonder if the hunting
has been really good and that's what he's out doing. But for days? Be
nice if we could put a little kitty-cam around his neck.

Do your cats have food and water available outside?  Anymore I don't even
feel like I have cats.  Except for the hassle of getting them in at night.
Charlie keeps water and cat food in the garage for them so they really don't
need to come in.

It was nice tonight.  They have both been in for 24 hours and they had a
good time playing together.

Abelard, go home to your Meowmie!

I think Abelard is probably jealous of the others. Purrs that he comes
home soon.

How old is Abelard?  Our Percy, aged 2, has been
doing the same thing for the last month few months.
I know where he hangs out -- there's a house on the
next block that is cat-friendly and has a couple of
intriguing bird feeders in the front garden. In
fact, I dropped off a bag of cat food there a couple
of weeks ago because I know the woman there is
feeding him.
 I've gone over there twice and have caught him
and taken him home. I've also walked/driven around
there countless times, and haven't seen him.
 I suspected that he was unhappy about one of
the other cats in the house; we foster for a cat
rescue group, and I know that he didn't like her.
However, he has been home since
she left, but has still gone on walkabout again.
 Every time we get him home, we are determined
that he's going to stay in the house, but the little
scamp is very sneaky and fast. He knows that he
has to outwit us, and he does!
  I think that, for some cats, the age of
2-ish is a time of adventure and daring. I've seen
it before, and have seen the older cats become
happy to stay in or around the back garden.
  Still, it's worrying, and I do hope that
Abelard returns home soon. Percy carries a tag
with his name, address, and phone number on it,
and that gives me a little confidence that I'll
hear if anything happens. I put it on him because
he disappeared in February, when the temperature
was 'way below zero. I was frantic. I put up a sign
in a local pet store, and an hour later a woman
a few doors down called me to say that her mother
had let him in and he'd been living in her basement
for 3 days!

Was he your first cat and had you just to himself?  As a matter of interest,
if he was he might be upset about the others.
You know yourself that cats will leave home if they are not happy about
something.  Kitty FC did and came here.
There might be something that Abelard is not happy about and you must find
out what it is to get him back.
On the other hand, the weather might be so nice and the hunting so good that
he doesn't need you at the moment ;-)
My money is on that.

Purrs that Abelard will remember where "home" and love can be found, and
return to you soon, Pat. I hope he's okay.

Melissa

Please go home, Abelard!
Best wishes and purrs,

Sorry, no helpful hints, so am just sending some purrs for him to
return and stay awhile
