My 2 greys, both will be 15 years old later this year,act up and misbehave more than normal in the spring. But Nilah my amazon..that's a whole other ballgame...since she was 3 1/2, we have quite a time with her in the spring..I won't go into the details..but to say whe finds ways to "satisfy" herself anywhere..on the blanket, my shoulder your arm...it can be wuite embarrassing listening to her...she also gets more aggressive..All 3 of them will fight more over territory so I have to keep a watchful eye all thru spring when they are out. Nilah is 12 years old now, I do see signs of her being horny (for lack of a better word) slowing down. I hope this means the end is in sight, as I remember Ray, I think, telling me they calm down around the age of 12 or so...???
