BEWARE OF POISONOUS PLANTS!
by Di Rees BVetMed MRCVS

We recently had to treat two separate pairs of guinea pigs who made the mistake of making a meal of poisonous plants whilst out foraging in the garden. The guinea pigs were all very weak, hypothermic (low body temperature), and had a very slow heart beat. They all needed intensive care for 48 hours and fortunately made a full recovery.



Although we cannot be certain, we suspect that the guinea pigs had ingested the leaves of foxglove plants.  Foxgloves were traditionally used to make heart medication for humans (digitalis) but can be deadly if too much is eaten.  The entire plant is toxic (including the roots and seeds), although the leaves of the upper stem are particularly potent.  Unfortunately there is no antidote and when we suspect a case all we can do is support them medically.  This involves maintaining their body temperature and hydration, administering painrelief and syringe feeding them as they normally are anorexic (not eating). If you are worried that your guinea pig has ingested this toxin please do not hesitate to call us for advise or book an appointment.

Other garden plants that are poisonous to guinea pigs:

Fortunately most grazing animals instinctively recognise poisonous plants and will avoid them; but to eliminate the risk of poisoning always ensure your guinea pig does not have access to any of these plants.

Guinea pigs make lovely pets and are rarely aggressive towards humans. An ideal diet for guinea pigs should comprise good quality guinea pig pellets (do not feed ‘muesli’-style foods), hay, grass, fresh fruit and vegetables. And don’t forget fresh water!
