We live in Austin, Texas (US). My 2-year

Answer

I'll handle this carefully. This is a known veterinary emergency and your roommate's instinct, while understandable about cost, is the wrong one. Let me get the facts straight from the closed tables before I answer.

Confirmed: Easter lily (true lily, *Lilium* / *Hemerocallis*) is toxic to cats — "renal failure and death are both possible." Easter Lily Cactus also came up but is non-toxic; a "flower bouquet with a green leaf" is the true lily. Let me check the species card.

The card is clear and the closed table has no animal-poison hotline for Austin this turn — that means vet_fallback only, no number printed. Let me draft and validate before sending.

**Yes — this is a true veterinary emergency. Take him to an emergency vet right now, tonight. Do not wait for symptoms.**

**Short answers to your three questions:**

1. **Yes, even with zero symptoms.** True lilies (*Lilium* / *Hemerocallis* — Easter, tiger, stargazer, daylily) are acutely nephrotoxic to cats. Published guidance says **1–2 leaves, petals, or even a brush of pollen can cause severe acute kidney failure.** Cats are the only species affected this way; dogs are not. The ASPCA lists the outcome as "vomiting, loss of appetite, lethargy; renal failure and death are both possible."
2. **Why "wait and see" is fatal.** The toxin damages the kidney tubules. There is a deceptive silent window of about **12–72 hours** where the cat looks and acts completely normal — purring, eating, even playful — while kidney injury is already underway. By the time vomiting, lethargy, or appetite loss appear, the damage is often advanced. The decontamination + aggressive IV-fluid window that actually saves the kidney is in the **first few hours**. Once a cat reaches the "not making urine" stage, prognosis is poor even with treatment.
3. **ight now — and no, do not induce vomiting with hydrogen peroxide.** The cat toxin guidance is explicit: do not induce vomiting or give medication at home. Hydrogen peroxide can burn his stomach/esophagus, and a cat vomiting lily material at home risks aspiration pneumonia. The vet decides whether/how to decontaminate (usually emesis + activated charcoal + IV fluids for ~48 hours).

**Do this in the next 5 minutes:**

- Put him in a carrier and **go to an emergency veterinary clinic now**. Call ahead on the way so they can prep.
- Bring with you:
- The chewed leaf (with the bite mark)
- The rest of the bouquet if you can grab it
- Time of exposure (~20 minutes ago)
- His weight (~4.5 kg)
- Photo of the plant from the florist tag if there is one — species confirmation matters
- Any vaccine/medical record you have

**Do not:** wait for vomiting/lethargy, give hydrogen peroxide, milk, or any home remedy, "dilute" with water, or wait for your regular vet to open tomorrow.

**About your roommate's $1,000 concern — it's a real worry, but the math is the wrong way around:**

- The bill for a true lily case (48 h IV fluids + monitoring + repeat bloodwork) often does hit four figures. That's honest.
- Waiting until symptoms appear is **far more expensive** (dialysis if it's even an option), **far more likely to fail**, and the cat can die.
- Many E clinics take **CareCredit** or offer payment plans; humane societies and a few national funds help with emergencies; pet insurance (if you have it) covers toxic exposures.

The medical decision can't be driven by the price tag, because the cost of *not* going is the cat.

The animal-poison hotline table has no confirmed line for Austin this turn, so the local emergency vet is the first call — any 24-hour E in Austin is the right place; if you need a referral, call the nearest E on your way out the door.

This is one of the few cat emergencies where how he looks right now is genuinely misleading. The clock that matters is the kidney clock, and it started 20 minutes ago.
