We put out some food & water for the kitties yesterday morning because we felt bad for them especially in the heat. Looking back, maybe that was a mistake. They ate a little and drank some.
I couldn't get a hold of the Humane Society until about 3PM yesterday and by that time the kitties had gone. I don't think they went far but we didn't find them. The Society said they would take them and try to find homes if I brought them in. What I've read on the 'net is that I'm suppose to bring in the mom as well so she could be spayed. The HS said I could rent cat traps (don't know what those are or how they work) but they didn't have any available at the moment.
I guess the cat(s) came back from time to time yesterday evening (maybe looking for more food) because every couple hours the dog would go looney - jumping on top of tables trying to get closer to the windows. I'd look outside to see if I could get a hold of them but only caught a glimpse of the mom once and she wouldn't come near me.
In the meantime, we let the dog out to "do his business" only when we're fairly certain the cats are not nearby. When he does get out, he tracks the cats and finds were they were.
DH doesn't think the dog would do anything if he caught up to the cats but I'm not certain.
