A difference between gets() and fgets() is that fgets() leaves the newline in the buffer. So instead of checking whether the first element of the input is 0, check whether it's '\n';

fgets(cat[i].name, sizeof cat[i].name, stdin);
if (cat[i].name[0] == '\n' || cat[i].name[0] == 0) {
    // empty line or no input at all
    break;
} else {
    // remove the trailing newline
    int len = strlen(cat[i].name);
    cat[i].name[len-1] = 0;
}
