Core vaccines are the essential, don’t-pass-on-these vaccines. And they include things such as rhinotracheitis, which is a herpes virus. There’s calicivirus, feline leukemia is actually now considered a core vaccine, and rabies. So those are the big ones that, regardless of your cat’s lifestyle such as whether they live indoors or outdoors.

Non-core vaccines are the opposite of what I just described. There are vaccines that may not be necessary in every cat and your cat may not need them if that’s the case. So, first off, if you have an indoor cat, is he going to need things like FIV, feline immunodeficiency? Yeah, probably not. He has to get that through the bite wound of an infected cat. How’s that going to happen if he lives indoors 24/7? So, that’s a non-core vaccine.

Might it fit the lifestyle of a barn cat living out in the country who’s with 20 other barn cats and likely to be getting into fights? Absolutely, it would be recommended there. So it depends on the cat’s lifestyle. Other non-core vaccines are things like feline bordetella, calici, and chlamydia. Those are about the only three I can think of right now, but those are non-cores.

Typically at their first visit, depending on when that visit is. I typically recommend the first visit be at 6-8 weeks, which is usually right after the time of acquisition of the kitten. And then those vaccines are boostered approximately every 3-4 weeks after that until about 4 months of age.

Some are public health concerns. Rabies. I know that your cat is only going to get rabies by being exposed to a rabid animal. It’s probably not going to happen indoors, but what happens if your window pops open, or your window is open and the screen pops out and your cat wants to take off? You can’t afford to risk those types of things. A disease like rabies, for example, is a human threat. If, by some chance, your cat gets out, gets bitten by a rabid animal, and comes back home, they will likely act fine for quite a while. But then on about day 9 or 10, your cat is not acting quite so fine. You see where I’m going with that? There’s no point in allowing that to even be a possibility.

So for certain public health concerns, there’s that. And again, even other viruses that I didn’t mention in that scenario could involve the same exact thing happening. Say your cat’s indoors and you think to yourself, “Oh, I don’t want to do feline leukemia.” What happens if he gets out? What happens if it’s a pretty fall day and there’s another cat that comes nose to nose with him at the screen. They didn’t even come into direct contact, but can it be transmitted that way? You bet it can. So that’s the reason why it’s still important.

It kind of depends on the age of the kitten, number one, as well as how long of a gap there is. So first off, what do I mean by the age of the kitten? I like all animals, dog or cat, to have at least 2 sets of vaccines after they are 10 weeks of age. I also said earlier that I like to vaccinate every 3-4 weeks. So what happens if one time you’re late and you can’t come in for six weeks? Not a problem. Get them in when you can. It just can’t be any closer together than three weeks, as you won’t get the right immunologic response.

It depends on where the cat lives and what vaccines they’ve had prior to that, and the age they are. So let’s say your cat got vaccinated at 10 weeks and again at 14 weeks, and maybe your veterinarian wants to do one more at 18 weeks. You’re close. Can that cat go outside? I’ll answer it this way. I usually err on the side of caution, so I would rather that your cat not be exposed until I can be more certain and you can be certain that they are protected.

If in my previously mentioned scenario, would I expected them to contract something that they were vaccinated for? No, I would not expect, but vaccines are not 100% foolproof. So when in doubt, keep them indoors until they are fully vaccinated.

The most truthful answer is people that don’t handle vaccines for a living don’t always know how you’re supposed to handle a vaccine. The biggest example of this are feed stores—that’s what we run into here. They deal with feed, with all due respect. They have a very important role, but their job is not to vaccinate animals. So when they get a shipment in, they don’t know to look to see if that thing was stored below X degrees. The vaccines have to be refrigerated. They have to be stored under refrigeration without fail. Sometimes those things are not there when the vaccines are not from a veterinarian.

On the veterinary side, we are ordering from veterinary specific vendors that ship and package them properly. They arrive refrigerated and at the proper temperature, we immediately know how to handle those things. And if ever there’s a situation where that shipping process was not satisfactory, we send it back and we get the right shipment to us. So there’s no way to get around that. I would never imply that the vaccines from a feed store are ineffective. It’s just, I personally want the reassurance and peace of mind to know that they were handled by animal healthcare professionals.
