Hello!

I did some searching around for a subreddit to ask this question in, but this was all I came up with. If there is a better place to ask this question, please direct me there!

On to the actual question...

On Friday, my girlfriend and I adopted a 3-year-old cat from her grandmother as we moved into our new apartment. We set her litter box up in the spare bedroom along with a bowl of water, wet, and dry food (the same brand she ate at grandma's house) and have been keeping her shut in this room. 

At first she was understandably extremely scared of us and cowered into the corner, but we tried to spend time in the room just talking to her and getting her used to our presence. She began to warm up to us and when we sit in the room for a few minutes, she'll come up to us and let us pet her for as long as we want. Yesterday we even got her to play with some toys we put out. I've cleaned her litter box every day so far, and she has been "doing her business" in there.

The concerning part is that she has not eaten since the morning we picked her up (Friday, Aug 21st). We have tried giving her fresh wet food on a few occasions and have offered her treats. She sniffs them a little bit and then seems uninterested. Last night she licked her wet food when we set it out but then turned away.

I've googled the issue and read many responses about some cats needing a long time (weeks in some cases) to come out of their hiding spots. All of them said that when they feel comfortable, usually at night, they will come out to eat and "do their business." This just seems very odd to me, because she is obviously getting comfortable enough with us to come out of hiding, but still won't eat.

This turned out really long, but my question is should we be concerned? When should we contact our Vet to get some suggestions?
<bot>: New cat (3 yrs old, had her since Friday) will come to play with us, but has not eaten anything. Should I be concerned?
