Every cat owner has experienced it: you’re eating something, your cat stares with laser focus, and you wonder — can my cat have some of this? The answer depends entirely on what “this” is. Some human foods are perfectly safe and even nutritious for cats, while others are dangerously toxic.
This evidence-based guide covers 50+ common foods so you always know what’s safe and what could send your cat to the emergency vet.

✅ Safe Foods for Cats
These foods are safe to share as occasional treats (treats should be <10% of daily calories):
Proteins
| Food | Notes |
|---|---|
| 🍗 Cooked chicken (plain) | Excellent — lean protein, no bones, no seasoning |
| 🦃 Cooked turkey (plain) | Great — similar to chicken. Remove skin and fat. |
| 🐟 Cooked salmon | Good — omega-3s benefit skin/coat. Never raw (parasites). |
| 🐟 Cooked shrimp (plain) | Safe — remove shell and vein. High in protein. |
| 🥚 Cooked eggs | Safe — scrambled or boiled with no butter/oil. Never raw. |
| 🐟 Cooked tuna (occasional) | Safe in small amounts — too much causes mercury buildup and “tuna addiction” |
Fruits
| Food | Notes |
|---|---|
| 🫐 Blueberries | Safe — antioxidant-rich. Most cats won’t care for them though. |
| 🍉 Watermelon (seedless) | Safe — hydrating treat on hot days. Remove all seeds. |
| 🍌 Banana (small pieces) | Safe — high in sugar, so keep it minimal |
| 🍓 Strawberries | Safe — remove leaves. Cut into small pieces. |
| 🎃 Pumpkin (plain, cooked) | Excellent — great for digestion. 1 tsp helps with hairballs and constipation. |
Vegetables
| Food | Notes |
|---|---|
| 🥕 Carrots (cooked, small pieces) | Safe — cook until soft (raw is a choking hazard) |
| 🥒 Cucumber | Safe — hydrating, low calorie. Some cats love them fresh. |
| 🥦 Broccoli (steamed) | Safe — small florets only. Good fiber source. |
| 🫛 Green beans (cooked) | Safe — plain, no seasoning. Good for weight management. |
| 🌿 Cat grass (wheatgrass) | Safe — helps digestion and satisfies the urge to chew greens |
⚠️ Safe in Moderation (Don’t Overdo It)
| Food | Limit | Why to Limit |
|---|---|---|
| Cheese | Tiny amount, rarely | Most cats are lactose intolerant — causes diarrhea |
| Plain yogurt | 1 tsp occasionally | Lower lactose than milk; probiotics may help digestion |
| Cooked rice | Small portion mixed with protein | Not nutritionally meaningful for cats, but safe |
| Bread | Tiny piece rarely | Empty calories, no nutritional value |
| Peanut butter | Tiny lick only | High fat, possible xylitol danger, choking risk |
| Tuna (canned in water) | 1–2 times/week max | Mercury buildup, can cause addiction, nutritionally incomplete |
| Liver | Very small amounts | Too much causes vitamin A toxicity |
🚫 Toxic & Dangerous Foods — NEVER Feed These
These foods can cause serious illness or death in cats. If your cat ingests any of these, contact your vet or the ASPCA Poison Control Hotline: (888) 426-4435 immediately.
| Food | Toxic Effect | Danger Level |
|---|---|---|
| 🧅 Onions (all forms) | Destroys red blood cells → hemolytic anemia | 🔴 HIGH — even powder/cooked |
| 🧄 Garlic | 5× more toxic than onions — same mechanism | 🔴 HIGH |
| 🍇 Grapes & raisins | Acute kidney failure — even small amounts | 🔴 HIGH |
| 🍫 Chocolate | Theobromine toxicity — vomiting, seizures, death | 🔴 HIGH (dark choc worst) |
| ☕ Coffee & caffeine | Rapid heart rate, seizures, tremors | 🔴 HIGH |
| 🍺 Alcohol | Even tiny amounts cause liver/brain damage | 🔴 CRITICAL |
| 🫒 Xylitol (sugar substitute) | Liver failure, hypoglycemia, seizures | 🔴 CRITICAL |
| 🥑 Avocado | Persin toxin — vomiting, diarrhea | 🟡 MODERATE |
| 🥜 Macadamia nuts | Weakness, vomiting, tremors, hyperthermia | 🟡 MODERATE |
| 🌰 Raw dough (yeast) | Expands in stomach + produces alcohol | 🔴 HIGH |
| 🦴 Cooked bones | Splinter and perforate intestines | 🔴 HIGH |
| 🥛 Milk | Lactose intolerance → diarrhea, stomach pain | 🟡 MODERATE |
Toxic Plants That Cats Often Chew
- Lilies (ALL types) — Extremely toxic. Even pollen on fur can cause fatal kidney failure. The most dangerous plant for cats, period.
- Poinsettias — Mild irritation (less dangerous than commonly believed)
- Pothos/Devil’s Ivy — Mouth irritation, drooling, vomiting
- Aloe vera — Vomiting, diarrhea, lethargy
- Sago palm — Liver failure, potentially fatal
Safe Drinks for Cats
- Fresh water — Always available, changed daily. Cats prefer running water (consider a fountain).
- Cat milk (lactose-free) — Specifically formulated for cats. OK as occasional treat.
- Bone broth (plain, no onion/garlic) — Great for hydration and picky eaters. Warm it slightly.
Dangerous Drinks
- Cow’s milk — Most cats are lactose intolerant after weaning
- Coffee, tea, energy drinks — Caffeine is toxic to cats
- Alcohol — Even a tablespoon can be dangerous for a small cat
- Fruit juices — Too much sugar, often contain additives
5 Rules for Sharing Food with Your Cat
- Treats ≤ 10% of daily calories. A 10-lb cat needs ~200 calories/day. Treats should be 20 calories or less.
- No seasoning, ever. Salt, garlic powder, onion powder, butter, and oil are all problematic.
- Always cook meat and eggs. Raw food carries salmonella and E. coli risks for both you and your cat.
- Introduce new foods one at a time. Monitor for 24 hours for vomiting, diarrhea, or allergic reaction.
- When in doubt, don’t. Your cat’s complete nutrition comes from their cat food — human food is a bonus, not a requirement.
Frequently Asked Questions
Can cats eat dog food?
A bite won’t hurt, but dog food should never replace cat food. Cats need taurine, arachidonic acid, and higher protein levels that dog food doesn’t provide. Long-term feeding of dog food can cause serious nutritional deficiencies including blindness and heart failure.
Can cats eat raw chicken?
While some raw-feeding advocates promote raw chicken, most veterinary organizations (including AVMA and AAFP) advise against it due to salmonella, E. coli, and parasite risks — to both the cat and human family members. Cooked, unseasoned chicken is the safer choice.
My cat ate chocolate — what do I do?
Call your vet or the ASPCA Poison Control Hotline (888) 426-4435 immediately. Note what type of chocolate (dark is most toxic), how much was eaten, and your cat’s weight. Do not induce vomiting unless instructed by a veterinarian.
Why does my cat beg for food constantly?
Constant begging can indicate: boredom (cat needs more mental stimulation), worms (get a fecal test), hyperthyroidism (blood test), diabetes (blood test), or simply learned behavior from being rewarded with food. If the begging is new or associated with weight loss, see your vet to rule out medical causes.
