First of all, welcome to RF!
I'm Summer, I'm 12; I'm in the exact same position of you, minus a younger sibling and a kitten, of course x3 [[Edit: Well I do have a little sister, but she's only 3 years old.]] I'd be in an asylum if I ever told my mom about the Fae…
A kitten won't affect the Fae much, though certain fae may be attracted or unattracted to animals. [[Think of people who like cats and people who don't hate them but don't love them]]
Some popular ways to attract faeries are to:
1. Make a faery house! It can be any size and can be put indoors or outdoors, but don't put anything containing iron in it, they're all very allergic to it.
2. Leave out offerings of food or pretty stones. Faeries love sweet stuff, mostly fruit. And most favor lemon- but all faeries have different taste, so anything left out can help! Most love honey and milk- but the problem with that is ants. Faeries love anything pretty. They also like it when you leave out clothing and shoes and etc. If it isn't gone, don't be disheartened- they can take the essence of things but not take things physically.
3. Put up the faery flag somewhere! If your parents ask what it is, just tell them your friend made it for you or something. You can find a few copies of it all over the site.
4. Protect against Unseelie [[bad faeries & entities]]! If you do this, the Seelie [[good fae and entities]] will feel more inclined to enter your home. There's an elven protection rune somewhere around here, you can print it out or simply draw one [[doesn't have to be fancy!]] if you like. They work for me!
5. Invite the fae into your home and mind! Most fae don't appear or use their voice physically. You'll have most encounters within your mind or dreams. You'd be suprised how much doing this helps- inviting them into your mind. [[invite only Seelie, mind you]]. If you hear something, it may seem like it's just you making things up, but most likely, it isn't.
I have some other things to say, too, I'll add on to this list sometimes soon :3
Hope I helped!
Thanks!
