Consulted references classify the plant as toxic or irritating for that pet type.
Vomiting, diarrhea, lethargy, and changes in urine color.
Ingestion can lead to gastrointestinal irritation. Please contact your veterinarian if your cat has consumed any part of this plant.
Move your cat away from the plant and pick up any chewed pieces so she can't go back for more. Do not induce vomiting at home — Pet Poison Helpline specifically lists owner-induced vomiting as a misconception to avoid. Call your vet or Pet Poison Helpline at (855) 764-7661 before giving anything by mouth.
Most common: vomiting (often the first sign), followed by diarrhea, lethargy, and loss of appetite. After a larger ingestion you may also see a reddish or brown tint to the urine. Muscle tremors are reported but uncommon.
GI signs typically begin within a few hours of chewing aloe and usually resolve over 24–48 hours with supportive care. Exact onset is not precisely documented in the cited sources.
Call your vet or ASPCA Animal Poison Control at (888) 426-4435 if your cat vomits more than once, has diarrhea, becomes withdrawn or lethargic, or you notice any pink/red color in the urine. Treat any chew of a whole leaf as urgent rather than wait-and-see.
Aloe vera is toxic to cats. The clear gel inside a mature leaf is mostly inert, but the bitter yellow latex just under the skin is loaded with saponins and anthraquinone glycosides — and cats are particularly sensitive to those compounds, which act as strong emetics. Even a small chew can lead to vomiting and lethargy.
