My father found a two kittn from upstairs , and gave it to us to tke care of it . So we took care of it and that night the momma cat get the fat and left the skinny one , so we decided to put the skinny one upstairs so the momma cat get him. But since he cant meow i played a meow sound on youtube but she doesnt come back , so we decided to take him in becausw it cold , and i took care od him until last night when i feed him milk , he started making sound like choking when breathing , with high pitch sound , and sometimes he open its mouth , i dont know what to do so i rub his back back and forth , but mostly upward to make him get the milk out , i was wprried and started crying , but i manage to stay calm and search and ask some friends , but i cant see anything , and i let him sleep but his abdomen is getting big when inhaling that it wakes him up and chenge his position and place to sleep , his paws are cold , i just watch him while he was sleeping until morning 6 am i decided to feed him again because he is awake , ang started doing it again so i stoped, i am asking what to do , i dont know if should i feed him , i contacted a onluine vets but they are not responding until now , i can fo out because of strict community quarantine even its emergency, i didnt get any sleep and i am hurting if im seing him breathing like this ,
