I adopted a kitty need advice?

I went to a shelter today and adopted a kitten. She wasn’t in the shelter, she was with a foster mom and we met at the shelter and did the adoption through the shelter. She’s already litter trained and used to people. She’s been with me for about 4 hours.

She’s been very curious and excited exploring.

1. I cannot explain how inlove I am right now. She has completely taken to me and has cuddled and snuggled with me and just immediately accepted me as her human.

2. I’m a little worried though because I have a litter box set out plus food and water. She sniffed it for a moment and went off to play again. So she hasn’t gone pee or poop or eaten since she’s been here. Do you think it’s because she’s excited? She’s acting perfectly fine. Currently snuggling me foot

All my kitties were rescued strays so they took to food immediately and pottied in the floor so I had to litter train them at first. She just hasn’t bothered doing anything but snuggles and play. So I’m like... huh

Sincerely worried new cat mother

Update; she had a bath and ate some food and now she’s kneading a blanket. I think she’s feelin pretty comfy now. I forgot to add she also used the litter box! I’m so happy about it lol
