Unless you are very close with the cat, even at that nothing is guaranteed. Cats just cannot be compared with dogs when it comes to human interactions.
These are things that can be noticed if you pay attention to your cats and are concerned about their wellbeing. You are responsible for them so you have to do your best to take care of them.
Yes, you know how cats can be territorial. You will just see that they are taking ownership of everything in the house and you have nothing to yourself anymore.
Cats are said to be the most curious of all living organisms, and they always display it quite alright. They have that laser focus attention on what you don’t even understand.
You have to plan and schedule your time well for you to achieve that, if not you won’t be able to get it done. You will thank yourself for it eventually.
