Your cat is going to need a quiet safe space where it can hide as it might do so during the first few days after being adopted. This is completely normal and it will warm up to you eventually. Additionally it needs a comfortable bed where it can take naps. Do not get frustrated if a cat does not use the items you bought for it and try using food to attract it to them.
