Rachel,
I don`t know but I am sorry. I hope you can get home soon. I know sometimes my outside feral cat will not come and eat for a whole day and half when it real cold out like now but then she does come eat and seems fine.
I know this winter could not get over fast enough for me its about -10 here right now.
When do you think you will be able to get home and feed them?
Terri
