How to keep my current cat safe when adopting a new kitten?

As long as you are sure your cat was vaccinated the risks are very minor, vaccinated cats very very rarely contract the disease. i would still recommend keeping them apart until the new cat is completely recovered.

I'm so sorry that your last cat passed away from panleukopenia. This is a parvovirus that is passed through various secretions and can survive fairly readily in the environment. As a result, it's virtually impossible to fully disinfect all materials - particularly carpet, rugs, and upholstered furniture. Hard, nonporous surfaces are much easier to disinfect with bleach diluted with water 1:32 and left on the cleaned surface for at least 5 minutes. Since this parvovirus can survive for up to a year, I would not take the chance of bringing Rag home until he's completed his entire vaccine series. I hope that everything goes well! https://www.petcoach.co/cat/condition/panleukopenia/

Feline parvo, also called panleukopenia, can be spread through the stool, urine, or nasal secretions of affected kittens. I'm glad you kept the kittens separated when they were both in your care. I would make sure you do not let your heathy kitten use any of the bowls, blankets, beds, or litter pans the sick kitten came in contact with. You can clean these items with diluted bleach. Also clean surfaces the sick kitten came in contact with similarly. Signs to watch for include lethargy, diarrhea and poor appetite.

I'm glad you are doing your homework before bringing new fur babies into the situation. Most shelters will routinely deworm their pets and test for leukemia and FIV. So you definitely want to make sure these treatments/tests are run prior to adopting the new kittens. Its not unusual for new cats and kittens to break with upper respiratory infections within the first 2 weeks of being adopted. Herpes virus is very common in cats (some estimate 80% of cats carry the virus) and it comes out in the stress related to being in a shelter and being rehomed. Now, this is not going to happen to every cat/kitten but its not unusual. Therefore, your best chance to avoid this would be to get a cat/kitten that has been kept in a foster home. It will likely still have herpes but the environment should be less stressful, therefore less risk of the virus becoming active. Keep the new pet separated for 2 weeks. That way if it does have an outbreak, you will at least have it contained. You could also put your cats on 500mg of lysine twice daily to help booster their immune system. Kittens get 250mg twice daily. Please post again if you have any further questions!

I would worry a little more about the new kitten passing on diseases to the older cat - viral upper respiratory infections in particular are common. I'd recommend vaccinating both cats with the FVRCP combo and rabies vaccines. If the cats are going to continue to be outdoors then the FeLV vaccine would also be recommended, and I actually usually recommend vaccinating all kittens for FeLV since you never know if their lifestyle might change.

This is great. I would freshen up your Angora cat's vaccination and when you adopt your new kitten, make sure it is examined, wormed and vaccinated by your veterinarian. All should be well then. Oh, and there will be a lot of hissing and spitting....do not despair. It will take time but eventually they will at least tolerate each other or even like each other. Make sure you give your older kitty just as much loving as up to now so she does not feel neglected.

Because Jiji hasn't been vaccinated before, she will need at least two rounds of vaccines given four weeks apart in order to have full immunity. Vaccinating her on Monday will not be enough to protect her. Make sure your dad fully cleans the room, and bring your own food and water bowls as well as litter box so that she doesn't share anything with his cat. Keep your kitten in the room, and allow her to have no contact with the other cat. I do recommend getting her vaccinated, so have her seen by the vet on Monday to start the process. Best of luck!
