Watch for

Why it happens

Unknown nephrotoxin in all Lilium and Hemerocallis species

Recommendation

NO lilies in any home with cats. Ever. This includes Easter lilies, tiger lilies, Asiatic lilies, daylilies. Even brief pollen contact can be fatal. If exposure suspected: emergency vet immediately + IV fluids for 48-72h.

Urinary blockage in male cats — emergency
