I'm posting this about my sister's cat, Peasy.  Last Thursday my sister took
Peasy to the vet for a regular checkup/shots.  Peasy is an indoor/outdoor
cat so my sister makes sure she gets her vaccinations each year.  My sister
called me up, very upset, about Peasy's behavior since the shot.  I think
she said it was a leukemia shot, but I can't remember.  The vet told her
that it was a new shot they were using now, and that it would be
safer/better etc.

After taking Peasy home and through the rest of the day and into Friday, she
said that Peasy wouldn't eat or drink and just climbed into an
out-of-the-way spot to sleep.  My sister said that Peasy felt really warm to
her, and she called the vet who said to bring her in.  She said the vet gave
Peasy another shot (cortisone?) and told her it would counteract the
vaccination.  Does this mean that Peasy is no longer protected, and will
need to be re-vaccinated?  My sister said she won't let them give another
"new" shot and wants the old one back, because Peasy has never had a
reaction before.

When I spoke with her yesterday, she said that Peasy has been
eating/drinking & using the litterbox normally.  She said that she was
playing, but just doesn't seem to have the spark she used to.  The vet said
that as long as she's back to eating & drinking water and using the box, she
should be fine.

My sister is worried about letting Peasy out now, thinking that she isn't
protected.  My sister's two kids are always leaving doors open, so it's hard
to keep Peasy in.  She pretty much only goes out in the summer.  Once the
weather gets cool, she doesn't like to venture off the deck.  She showed up
on my sister's deck 2 1/2 years ago as a half-grown stray (turns out some
neighborhood people divorced & moved away and left her behind) and is used
to going out, so forcing her to stay inside might not work.
