Hello everyone, new to the site. My family and I just adopted our first kitten (5.5 months) from a rescue shelter here in Pennsylvania. We were told when we saw her and met her the first time that she was skiddish but she did sit with us nicely, even sat with my 6year old with no issue. We brought her home the next day and put her in our bed room to get her bearings and plan on leaving her there for the first couple weeks as advised by the shelter. We do have an apartment so it's not very big and we only have 2 bedrooms hence the reason why she's in the room with us (I've read they should be in a room alone). To cut to the chase, anytime we try to get near her or talk to her she hisses and her hair stands up. She's been under the bed since we brought her home and has not eaten at all. She did use the litter box a few times but no food and very little water. She also cried/meowed most of the night. Obviously I'm chalking all this up to being in a new home with new people but the hissing is what kinda concerned me. Is this something that she will grow out of? We're giving her her space but also want to bond with her.. she shows absolutely no interest in play. Just stays curled up under the bed. Looking for any input or ideas as we are new to this and trying very hard to make sure she has a long loving life thank you!
