Can you get a guinea pig for your male rabbit?

Answer 1

Although your pet rabbit would "accept" a guinea pig companion, the habit of the rabbit to jump playfully when happy could cause serious internal injury or even death of the guinea pig companion.

If you want your rabbit to have a companion, the best choice is always another rabbit - however both rabbits MUST be neutered (or neutered and spayed if the companion is a female rabbit) to avoid fighting or breeding, along with saving you the other troubles that neutering can fix (some types of aggression in both genders, spraying in males and uterine cancer in females - unspayed females who are not bred from have an 80% chance of being diagnosed with uterine cancer by the age of five years).

Also the rabbits should be introduced carefully (if possible take your first rabbit with you to a shelter to let him choose his own companion, as this would be much easier to deal with), first on neutral territory, and ONLY if the introduction goes well on the neutral territory, THEN socialize them in a place that your first rabbit considers his. If this doesn't go well put the rabbit companion in a separate cage, or if the cage is big enough, divide it so that each rabbit takes up half the cage and does not need to cross paths with the other rabbit.
