about pet rat

Question
I have a pet rat and have recently noticed hair loss on his neck, there are small red scabs on and around this area, and on other parts of his body. Do you no what could be the cause of this and any possible treatment. Many thanks.

Answer
 The most likely culprit is an external parasite such as mites or lice.  Buy a single tube of puppy / kitten Advantage or Revolution from your veterinarian and, using a 1cc syringe or eyedropper, apply a single drop to the back of your rat's neck.  Clean out the cage really well, including all toys and accessories, and repeat the dose in two weeks.  This will get rid of any external parasites on your rat.  To prevent reinfection, avoid contact with other rats and freeze bedding to be used for 24-72 hours before putting it in your rat's cage.

 If this treatment has no effect, it may be an allergy, a psychological / behavioural disorder, ringworm, or various types of dermatitis.  In those cases, he should definitely see a vet for treatment.

 I hope your rat gets better soon, good luck!
