My two guinea pigs Tom and Jerry get on really well with each other in their hutch, but when they're outside in the playpen they chatter their teeth at each other and chase each other. The last time they were out I had to put my hand in front of Tom to stop him going for Jerry, which left me with mark, that was bleeding- he bit right through my jumper :| they are about 1 and a half years old and both male. I hope you guys can help because I feel so bad as I haven't had them in the run for a few days because I'm really worried about them fighting ![sad :( :(](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f622.png)
