Now let’s see if our cute and lovely guinea pigs can consume thyme.

Risks to Consider When Feeding Thyme to Guinea Pigs

  • Urinary complications – thyme contains calcium and this is the reason why it needs to be taken with precaution. The calcium is beneficial for the guinea pig only when they are very young and still in development. But, once guinea pig is fully grown, your guinea pig simply doesn’t benefit much from this mineral. In fact, if the cavy gets too much calcium in its system, it will have urinary infections, blood in urine, stones in kidneys and bladder or even pain during urination. If this is not treated in time, it can be fatal!
