Do Siamese cats have behavioral issues?

No, Siamese cats are not prone to behavior issues. But, like any cat, they can be demanding and quite vocal when they need attention and stimulation. Under-socialized Siamese cats may be prone to jealousy and territorialism in multi-pet households or when introduced to new animals. Proper socialization, slow introductions to other animals, adequate enrichment, and providing outlets for their energy can help mitigate potential behavioral issues in cats.
