I'm inclined to agree with Erigeron canadensis, or horseweed. It isn't listed as toxic to cats, but one of its lookalikes is. To be safe, I'd keep it out of reach of the cat. Still, if cat's are eating plants it can be a sign of nutrient deficiency or stress, if the cat is chewing on your plants you may want to look into it a bit.
Here is some information on the plant: http://ucjeps.berkeley.edu/eflora/eflora_display.php?tid=2312
