i need some input please. my cat which i love deeply is driving me crazy. do kittens that are 6 months old go threw the so called terrible two's like children? he is into everything from knocking things off the counters{he's up there when i'm not looking and jumps off just as soon as i start walking his way]to hanging from my door stops that are pasted on the walls, which he has pulled off 5 of them. he knows that he's not supposed to do these things because like i said just as soon as we approach he he stops. will he out grow this stage. i tell my husband that he is almost as bad as a child.
