I love my kitten sooo much. Do you know any signs to show her I love her?

Like anything! ;)

She will learn by herself that you love her.
Trust me, I have 2 cats. You play with them, fed them and carress them but only when they want, cats are very independent thou.

All you have to do is take care of her! :)

Spend time with her - Talk softly, be gentle, feed her, keep her water fresh, give her treats, play with her, take her to her vet check ups...

Take care of kittie, and they'll know!

My cats have this little ritual they do with me, they stare up into my eyes and I stare back, and we slowly blink at each other. I know it sounds silly, but after a few seconds of doing this at each other, the cat comes over, jumps up, and is ready to be rubbed down!

Cats also love cat treats :)

Don't declaw her!
