Yea most Siamese are high energy as kittens/young adults. My girl is 6 months and she is all over the place demanding attention 24/7. She’s clingy, but also insanely smart so she figures out how to get into areas she knows she’s not supposed to be. They do best in pairs so they stay entertained, and Siamese in general are very vocal cats. It can also depend on the personality of the cat but usually they mellow out with age. I guess it depends on the cats personality and the age. My girl is only affectionate in the mornings and then she’s like “pet me with your eyes only!” Haha! And she’s also too territorial for a buddy, so she does well as a solo cat. Just goes to prove that the personality differs. Hope that helps!
