Is Blue Prince Holly toxic to cats?

Yes — blue prince holly is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. ASPCA lists Holly (Ilex species) as toxic to cats and dogs, with saponins as the toxic principle. Although this male cultivar bears no berries, its leaves remain toxic and cause vomiting, diarrhoea, and depression if eaten, while the spiny foliage can mechanically irritate the gut. Keep clippings away from pets.

Keep clippings away from pets. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to blue prince holly.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
