Cat eating grass that was sprayed with weedkiller earlier...help!

[unlucky83]

Normally I don't use the stuff but feeling over whelmed by weeds and having some to use up I sprayed some today.
It is B&Q's 'verve' rip off Roundup. I haven't got the package here but it was keep away from pets and children until dry ...it is dry, let cat out and find it eating grass (weeds) that were sprayed earlier - chased her off and she started eating some more that has been sprayed (Should add here there is a whole overgrown lawn full for her to eat that hasn't been sprayed...
So does anyone know if it is now safe? Will it make her ill? What should I do?
She has disappeared now - probably very confused why I won't let her eat the grass...

I sprayed some weeds in our garden with similar and as soon as I let my little guy out afterwards, he went straight for them. No ill effects. I think as long as it was dry, you'll be fine. Keep an eye on her and call the vet if you see any poisoning signs (drooling, vomiting, lethargy, etc - google it if you're not sure)

Don't panic!

Thanks - that's reassuring. I can't see her at the moment ...was not impressed with me stopping her grazing..
(I'm trying to batch cook, cook a pie for tea, put up with a PIA teen and get another DC off to an activity - stupid cat picks its moments!!)
