Why is it dangerous to pets?
The aloin and anthraquinones in the yellow latex just under the leaf skin irritate the large intestine and act as a powerful laxative. The clear inner gel is far less of a problem.
Pets usually chew the whole leaf, so they get both — which is why the common result is vomiting and profuse diarrhoea.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of aloe-vera poisoning

- Profuse diarrhoea, sometimes with blood or mucus

- Loss of appetite, lethargy
- Dehydration if the diarrhoea continues
What to do right now
- Call your vet and report how much leaf was eaten and the pet weight.
- Offer water in small amounts to replace losses; do not force it.
- Do not give human anti-diarrhoeal medicine without veterinary advice.
- Keep aloe on a high shelf; cats will chew the leaves if they can reach them.
