That's the ticket folks ... The label is the law, Ya have to follow the MSDS and the Label when applying any "cide" Ya have to read the instructions.
Corrales, had you read the instructions you would have known about the issue to cats. I am very sorry they got so sick, but when this product is wet - well now you now.
To be honest, had you read the label you would have done it outside on a non windy day instead you used it on or near kitchen food surfaces.
Here is a lot of good Q&A about the treatment
