Old Guinea Pigs
can be quite aggressive, when a young one comes to live with it. Since they’re
quite set in their ways, when other Guinea Pigs come to live with them, the
elder may even attack, leaving the younger with dangerous wounds.
Proper steps must
be taken for introductions between Guinea Pigs with a lot of age difference,
especially with males (boars), who are very protective of their territory.
Females (sows) aren’t so protective, but it’s still exquisitely important to
take the necessary precautions listed below.
1 Rub the young
Guinea Pig in straw/hay/bedding from the older one’s hutch/cage.
2 Introduce them
in a box which the younger has been brought home in, as then it will be its
territory, for young guinea pigs are lenient about such matters.
3 Give the Guinea
Pigs a carrot or food of that kind, divided in two portions so that they will
have some form of distraction, so that the only things in their environment is
each other, for then matters will likely turn into a fight.
4 If they will
live together, make a place in the hutch/cage where the young one can go if the
old one begins to bully it.
5 If the
interaction doesn’t work out, board up the cage in half (making d\sure they
each have a place to sleep), so it can be shared.
6 Supervise
interactions each day, until they become friends (they will, it’ll just take
time).
7 When they become
friends, take down the wall between their rooms, and let them live together.
If you follow
these precautions, it will be highly likely that your guinea pigs will become
friends, but if they don’t, don’t worry too much thinking about it. It will
happen in the end- you just need to let them have sessions together every day.
Incidentally, males are always very protective- so probably they will fight.
Remember, in the end they will gradually become friends, and come to respect
each other.
A trouble which
has been found when introducing boars to younger boars, is that the younger cuddles
the elder excessively, which the elder puts up with at first, but gets annoyed
later. Don’t try to do anything, just let them sort it out themselves. They
know what to do about this.
