Is Common Rush toxic to cats?

No — common rush is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. Juncus effusus is not listed as toxic by ASPCA and is not known to contain toxic principles hazardous to cats or dogs. Wildlife including cattle, waterfowl, and small mammals readily graze or use the plant. No toxic compounds have been identified in the genus at concentrations harmful to pets. Treat as low-risk; as with any plant, large ingestion may cause mild GI upset.

Yes — the ASPCA lists common rush as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.
