Why some foods are toxic to cats
A cat's digestive system works differently from ours. Some human foods cannot be properly eliminated by their bodies.
A very sensitive metabolism
A cat's liver is less efficient at eliminating certain chemical substances. As a result, even a small dose can cause poisoning.
Foods that are dangerous even in small quantities
- Chocolate affects the nervous system
- Alcohol attacks the brain and liver
- Caffeine dangerously speeds up the heart
According to the ASPCA, some foods considered harmless to humans can cause seizures, heart problems, or a coma in cats. :contentReference[oaicite:2]{index=2}
| Substance | Effect | Organ affected |
|---|---|---|
| Theobromine | Nervous excitation | Brain |

Symptoms vary depending on the food ingested and the quantity consumed.

Some cats seem fine at first before their condition rapidly deteriorates.
