Oh don't worry - I've seen a lot of people miss the fact you can triangulate distant landmarks. By the time they have mastered the instructions on the first page to triangulate their own position they completely miss or forgot that there was a 2nd page right next to it detailing how to triangulate distant landmarks :)

Well you do have a three day reprieve before "Kitty" the creature begins to spawn in, while you have important ingredients in hand. So if you have placed then into storage and know exactly where to go, then you may live without the heart beat of Kitty chasing you.

Oh I meant that I thought that he spawns in certain intervals, like every x-y minutes he wasnt around me, he spawns, but a lot of spawns are tied to specific locations or when you have an important plant in your hand, like you say! I just happened to spend a lot of time around the ruins near the glowing plant location and he kept spawning very often, that made me think it's interval-based or somesuch! It's so tense once you hear the heartbeat.
