I'm so sorry to hear about the kitties. I'm not sure they have feeding stations for them anymore.
When we were there in January, I managed to catch one of the cats to bring to the vet. He was struggling to eat the food I put out for him. He drooled and could only eat out of one side of his mouth.
Celine (the manager) let us borrow her cat carrier thankfully. Sadly, the story did not end well for the cat. He had a massive salivary tumor under his tongue which was blocking his breathing as well as his ability to eat. We had him euthanized to spare him any more trouble. The vet near Cole bay was excellent by the way. He was soooo wonderful with both us and the cats. And didnt think I was too crazy when I cried after deciding to euth the poor guy.
I HOPE that the spray for the ants is not causing this problem for the cats. Maybe it will be temporary? I HOPE!
