I am a farmer and have numerous farm cats.  Unfortunately they do not
always do their job of catching mice, especially those mice that get
into the basement, and later into the main part of the house.

The problem occured last evening.  I went shopping and bought some bar
type (blue) rat & mouse poison to put in the basement (where cats are
not allowed).  I parked the car and went in the house.  Five minutes
later I walked out to the car and found three cats had gone into my
open car window, and found that the mouse poison package had been
ripped open and some poison shreaded up and eaten.  

I am not sure what to do.  I have over 20 cats, although I can
eliminate at least 14 of them because they were locked in the barn.
That leaves me with the possibility that 6, 7, or 8  of them may have
eaten the poison.  I will mostly put the blame on the three that were
in the car.  Those three I gave some peroxide to try to make them
vomit.  It was a struggle giving it, and my arms got torn up pretty
bad by the time I was finished.  So, I dont know if they actually did
vomit, but I did give them a full large syringe of the peroxide.  I
did hear one gaging and it sounded like vomiting, but which cat????
The whole incident was mass chaos after I found the problem, so there
is no way to know what all occurred.

I cant haul them all to the vet. I'll be lucky to even catch them
after the peroxide......
What should I do?  I read on a web site that they need vitamin K.
Should I just give all of them, or at least these three the vitamins?
Possibly add it to their feed?

Any suggestions???????????????????????

Thanks in advance for all help.

PS. I plan to contact the manufacturer of the poison and complain
about the lousy packaging.  They put a harmless CD or tool, or
whatever hard plastic (clamshell), but put the poison into a less than
paper thin plastic.  This is not right !!!
