So, i've just recently adopted a 2 year old cat from my local shelter. he was a dream at the shelter, he would love all up on me and let me pick him up, basically anything. now that hes been home for a few days though, hes been different. i know a change in environment can be stressful to a cat, especially coming to a home that already has 2 cats, (hes secluded in one room and the other cats are not allowed near the room, ive done a lot of research lol

). anyways, ive had him since friday evening, and its now sunday night. he used to let me pet him and would smell me but didnt initiate any reaction. now though, when i enter the room, he starts drooling excessively and gets very stressed out and almost makes himself gag. i dont know what it is, ive asked the girl i know at the humane society and she said its just stress, but its only when he sees me or if i stand up after sitting down with him. ive been playing him music for cats (has purr sounds and sounds that help soothe cats, like i said ive done my research lol) and it seems to be helping until i make any kind of movement. it makes me feel really bad because i love him so much and i just want him to love his new home but hes HATING it so far and i know it hasnt been that long but im wondering what i can do to help make this an easier transition for him... please help!!!!!

im wondering if something happened in a previous home that the shelter didnt tell me about, because he was an owner surrender..
