Roundup - poisonous for pets?

[Kfamr]

I would imagine if they step on the spot directly after it's been sprayed that it could be harmful. I wouldn't allow the kitties outside until after a few days it's been sprayed.

You should consult ChemLawn or someone who does it professionally. We have ours done for weeds and improved growth in this horrid heat, and they do have some all natural products if you request them. Trust me, it'll be cheaper than trying to spray Round-Up, which really isn't going to be effective on a whole yard, on the whole thing.
