Correct content. Isolate the sick animal from other guinea pigs by placing it in a separate cage. In infectious diseases, it is necessary to frequently change the litter and disinfect the cage and all items in it (see next section). The cage should be placed in a calm and not too bright place, where there is no draft. Do not deprive the guinea pig of contact with your family members, otherwise the animal, in addition to its illness, will also suffer from loneliness. 

With pain, guinea pigs do not make plaintive sounds. Only by the look of the animal, changes in behavior and appearance, you can determine how much it suffers. You can help your pet if you take good care of it and take proper care of it. 

Drink. A sick animal must necessarily consume liquid, otherwise its body will be dehydrated. Water or tea should be slowly poured dropwise from the side into the cheek pouch using a syringe without a needle. So that the animal does not choke, from time to time you should remove the syringe and slightly tilt the animal back. The syringe must be inserted from the side into the cheek pouch

Cell disinfection. As a mild disinfectant, the Oranex universal cleaner made from orange oil is well suited. This product is used undiluted or slightly diluted, has a pleasant smell and, as practice has shown, is absolutely harmless to animals. It is sold at pet stores. 

Applying the ointment. For small wounds, carefully trim the fur around the wound and apply calendula ointment to the wound. 
Trim your hair first, then gently treat the wound.

Eye treatment. If the mucous membrane of the eye is swollen, treat the corner of the eye three to four times a day with chamomile infusion (10 drops per glass of warm water), gently touching with a swab. Keep the animal indoors with dim light during treatment. 

Measures in case of allergies. If your veterinarian has determined what your guinea pig is allergic to, you can take appropriate action. 

• If you are allergic to hay, feed the hay feeder no more than the animal can eat in a day.
• If you are allergic to bedding, try using a biological bedding (available at pet stores).
• If we are talking about allergies to certain plants, such as salad, of course, you should not give them to the animal as food. Consider if it would be better to remove any “harmful plants” from the enclosure.

Restoration of strength to weakened animals. A recently recovered but still malnourished guinea pig should be given plenty of herbal green food, vitamins, oatmeal and wheat germ. As often as possible, give the animal the opportunity to walk in the fresh air, but do not allow the animal to overwork or catch a cold in the draft. Consult your veterinarian about vitamin or stimulant injection. When breeding guinea pigs, such measures are undesirable. 

Before and after surgery . A healthy guinea pig tolerates surgery, in particular castration, very well. A week before the operation, give the animal daily vitamin C, since due to the lack of this vitamin, it will take up to 4 hours to awaken the animal after anesthesia. Do not feed the animal 12 hours before surgery. During the operation, the guinea pig is very cold, so after the operation, keep the animal warm for several days, for example, under a lamp. You can feed the animal only 12 hours after the operation, while it is advisable to give it the best food in order to speed up the healing process.
