<human>: Hello

My cat is approx 2 years old now. Not neutered, no vet visits yet. I'm planning on getting her neutered soon. She is in heat right now, but has this 'few day' off thing right now wich means I'm letting her in my room (no peeing etc). Right now I'm drinking some beer and listening to some music with friends (quite loud). When i turned it down a little, my cat climbed up my chair behind me and bit the back of my head gently. She also did a weird meow that sounded similar as the one when you play with her and she's basically telling you to stop it. Quite high pitched sound. I did google it and found some stuff that said it might mean that she is not comfortable with it (the enviroment, music etc). Now i turned everything off here and she is sleeping here. It also happened few days ago but there was nothing going on then. I was just sitting by the window and she put her front paws on my shoulder, bit gently (held on for like 5sec and licked the hair a little). Both times, after that she was holding back a little.

She doesn't want to eat much lately. I've offered her 3 different cat foods + lots of 'peoples food'. She seems to be interested, but when i put it in her bowl - she just walks away. She has lost some weight lately and is quite thin. I change her water daily and offer her some milk (she is lactose tolerant, but i give her just a little so she could still enjoy it).

Can you condense the text into a few key points?
<bot>: My cat bites the back of my head quite gently, holds on for about 5 seconds while making the "stop it" kind of meow.
