hi well i haven't been on here a while because everything was going well until about a week a go. well one of our guinea pigs keeps chewing on the bars and i mean loads we have given him chew toys and attention but nothing worked. you see well my two guinea pigs started fighting so we tried putting wire mesh in the middle put they were really clever and kept getting to each other and fighting so we put them in different cages but he might now be missing his friend. so basically i need help. oh and we do put them together from time to time but they get all agressive again so plz help asap.:0:...
