How to get objects to start moving again after collision

Processing Coding Questions
1

Hi! I have 2 cats that float around until they stop when they come into contact with each other, which I called catFight();. I want them to start floating around again normally every time ‘m’ is pressed. I’m new so processing so any basic solutions would be awesome!

Bombay b1;
Scottishfold sf1;

void setup() {
  size(800, 600);
  b1 = new Bombay();
  sf1 = new Scottishfold();
}

void draw () {
  background(30, 85, 147);
  b1.display();
  b1.moveBom();
  b1.checkBomEdges();
  sf1.display();
  sf1.moveScot();
  sf1.checkScotEdges();
  catFight();
}

void catFight() {
  if (((b1.bound2>sf1.bound1 && b1.bound2<sf1.bound2) || (b1.bound1>sf1.bound1 && b1.bound1<sf1.bound2)) && ((b1.bound4>sf1.bound4 && b1.bound4<sf1.bound3) || (b1.bound3>sf1.bound4 && b1.bound4<sf1.bound3))) {
    //println("Fight");
    b1.xSpeed=0;
    b1.ySpeed=0;
    sf1.xSpeed=0;
    sf1.ySpeed=0;
  }
}

you mean like

void keyPressed() {
  if ( key == 'm' ) {  //_ move again ? away from each other ???
    b1.xSpeed=4;
    b1.ySpeed=-3;
    sf1.xSpeed=-1;
    sf1.ySpeed=1;
  }
}

pls check the settings???
