However first, let’s brush up on our information concerning the rabies virus itself.
Rabies Virus in Cats
The rabies virus can have an effect on any mammalian species and is transmitted by way of the saliva, normally by way of a chew, though contact with an open wound may result in an infection. Curiously, though cats are essentially the most generally reported rabid species in the US, there aren’t any recorded instances of cat-to-cat transmission of the illness.
The virus assaults the nervous system, producing indicators resembling:
- Inappetence
- Irritability
- Hiding
- Nervousness
- Aggression
- Wild animals might lose their concern of people
The illness will normally progress into two types:
- Livid (additionally referred to as “mad dog”) rabies, which incorporates pupil dilation, overt aggression, and attacking with the enamel and claws at slight provocation or loud noise.
- Paralytic (additionally referred to as “dumb”) rabies, which incorporates paralysis of throat and jaw muscle mass, extreme salivation and incapability to swallow, and lack of muscle management. These animals not often chew, however people can change into contaminated when inspecting the mouth.
Prognosis could be very tough, with definitive analysis requiring autopsy examination of mind tissue. Moreover, rabies can mimic a number of completely different illnesses.
Unvaccinated cats suspected of being contaminated with rabies should be euthanized instantly or saved in isolation for six months. Vaccinated cats should be given one other vaccination dose and intently noticed for 45 days. Hybrid cats, such because the Ocicat or Savannah cats, could be vaccinated towards rabies, however their vaccination standing will not be formally acknowledged, and if a hybrid pet bites a human, the regulation might require them to be euthanized to be examined for rabies virus.
Vaccination Is Key
With the excessive danger of transmission to people, significantly in its livid type, vaccination is an important step you’ll be able to take to guard your self and your cat, regardless of your state’s laws. Rabies vaccines are thought of to be extremely protecting towards an infection, with vaccine failure not often reported.
In line with the American Animal Hospital Affiliation (AAHA), the really useful vaccination schedule for cats is as follows:
- First vaccination between 8 and 16 weeks
- Second vaccination inside 12 months
- Subsequent vaccinations each 3 years; nevertheless, native legal guidelines might require vaccination yearly, or each 2 years.
An animal is taken into account to be totally protected 28 days after the primary vaccination, and instantly following subsequent vaccinations, offered they’re given throughout the really useful schedule. These dates have to be strictly adhered to, significantly relating to journey.
1-, 2-, or 3-12 months Vaccines—What’s the Distinction?
That is the place issues get a bit complicated, however stick with us. Firstly, we have to discuss adjuvants in vaccines.
Adjuvanted vs. Non-Adjuvanted
An adjuvant is a substance that will increase the physique’s immune response to vaccination, which is nice from a protecting viewpoint, however it’s what causes many of the unwanted effects of vaccination, resembling lethargy, fever, swelling, and ache. For cats, there may be an extra danger related to adjuvanted vaccines: feline injection website sarcoma (FISS). The vaccinations mostly implicated in FISS formation are these for feline leukemia virus (FeLV) and rabies virus.
To attempt to scale back the dangers of FISS, vaccine intervals have been altered to attenuate the dangers of sarcoma formation whereas sustaining excessive ranges of immunity, which is why most vaccines are really useful to be given each 3 years as soon as a cat has had their preliminary booster, about 12 months after their kitten vaccination. Though there are canine research which have indicated immunity can last as long as 8 years in some people, a steadiness should be struck between minimizing the potential dangers of hostile vaccine reactions and public well being implications.
A further step has been taken by the corporate Purevax, which makes use of a recombinant canarypox virus to soundly confer immunity towards FeLV and rabies, with out the necessity for an adjuvant. The FeLV vaccine is at the moment solely licensed for annual vaccination intervals, however within the UK, the rabies vaccine is licensed for 3-yearly re-vaccination, following the booster given 12 months after the first vaccination.
Within the US, there are two variations of the Purevax rabies vaccine: a 1-year and a 3-year injection, with the one distinction being the labeling. Primarily based on the differing legal guidelines that exist in numerous US areas, we will solely assume that the 2 formulations have been created to make it simpler for vets to adjust to this laws. Nonetheless, there are instances the place vets are solely utilizing the 1-year formulation, mistakenly believing that it offers higher safety than the 3-yearly vaccine.
So, Which Vaccine Is Higher?
Given the excessive stage of safety given by the non-adjuvanted Purevax rabies 3-year vaccine, there appears to be little question that that is the clear winner when it comes to minimizing dangers whereas preserving your cat and household protected. Nonetheless, for cats which have a well being situation or are immunocompromised, an adjuvanted vaccine might present higher safety, as non-adjuvanted vaccines depend on a powerful immune response to supply future safety.
Except for California, which requires cats to be vaccinated each 2 years after their preliminary course, vaccination necessities within the US seem like in accordance with the product getting used. Nonetheless, you will need to test together with your native authorities physique to make sure that you’re complying with their legal guidelines.
Most veterinary clinics will solely carry one or two vaccine manufacturers, so it’s possible you’ll must telephone round to seek out one which makes use of the vaccine you like, following the schedule set out by the AAHA. Speak to your vet about their suggestions and expertise, as there could also be different geographic and particular person elements to think about.
Last Ideas

Even if you happen to stay in an space the place rabies an infection is unusual, even a low danger is just too excessive on the subject of this virus.
Most of the issues of the previous relating to hostile reactions to vaccines, significantly with regard to cats, have been considerably lowered by way of altering vaccine schedules and the creation of a dependable, non-adjuvanted model of the rabies vaccine. Not like the non-adjuvanted FeLV vaccine, the Purevax rabies vaccine is definitely licensed for a 3-yearly dosing, giving a great compromise between minimizing unwanted effects and maximizing safety. Remember {that a} non-adjuvanted vaccine will not be applicable for cats with well being circumstances or compromised immune methods. In these instances, a 3-yearly adjuvanted vaccine could be the most secure possibility.
The complicated labeling and variation in state and native legal guidelines surrounding rabies vaccination could make it tough to know what’s finest on your feline member of the family, however hopefully, you should utilize this data to speak to your vet about your choices.
