According to the veterinary medicine resource this drug has been tolerated at doses up to 90 mg/kg with mild symptoms (anorexia and excessive drinking) in some cats. Callie would have to have eaten 450 mg of Famciclovir to see these symptoms, so she is well below this amount if she ingested 2-125mg tablets totaling 250mg. She should be fine, however you can also consult with pet poison helpline to talk it over with a certified toxicologist as well. But based on my minimal research she is below the toxic level for ingestion. I hope your sweet girl continues to do well. Take care.

Hello, Yes, this drug can be prescribed to be given orally to cats for the treatment of herpes. I'd recommend making an appointment with your veterinarian to discuss the best treatment plan for her. Special pharmacies can make oral medications in cat-friendly flavors, like tuna, and this can help make the medication experience much easier. Sometimes this disease is still going to require eye drops as well though. I'd recommend trying to train her and make the eye drop experience better with positive reinforcement, treats, toys, etc to maintain this condition best over time. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello. It sounds like Bean has an ear infection so the Baytril Otic would be used for that. Famciclovir is an anti viral medication generally used to treat feline herpes virus, a very common upper respiratory infection in cats. The Erythromycin Ophthalmic is an antibiotic for the eyes, so the vet is being very through in treating your kitties. Hopefully, everyone will be feeling better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! I would recommend making sure he does not have an underlying disease that may be predisposing him to these infections. Test him for feline leukemia (FeLV) and feline immunodeficiency virus (FIV) at your veterinarian's clinic to rule these possible causes out. Some cats will have chronic viral infections their entire life and we just treat these as they come. If you are not giving lysine supplementation and not giving Purine Fortiflora, I would definitely recommend doing so as both of these have been shown to lessen the severity and duration of the herpes virus flare ups. I would also consider an upper respiratory culture to make sure that there are no other bacterial causes that may be resistant to the antibiotics currently being given. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

There is no treatment for corona virus. Although there is a vaccine, the cat would need to have received it before becoming ill with the virus. Supportive care to treat the symptoms are the best option at this point. Antibiotics would only be effective if there is a bacterial infection. If the vet in Russia has determined that there is a bacterial infection, they will be able to prescribe an antibiotic such as Clavamox. However, you will not be able to purchase antibiotics here to send to another country. If the cat becomes dehydrated, the vet will want to administer intravenous (IV) fluids. This is not something that can be done at home. Oral steroids such as prednisolone can sometimes be helpful but again, these would need to be prescribed by a vet in Russia.
