Lump at rabies vaccination site

My 4 month old kitten Maeby had her rabbie vaccine exactly 1 week ago. Today we noticed a lump at the injection site. The injection was given right between the shoulder blades, which I have since read is no longer considered the proper place for vaccination. The vet I have I trust completely as he helped us greatly with our Eeyore who passed away last year due to kidney failure, but reading that the shoulder blade injections are advised against now has me worried.The lump is firm, but not hard. It slides around very easily if pushed and doesn't seem to bother Maeby at all. She reacts to me messing with it just like if I was scratching her back, just rolling around and purring. We brush our cats daily so I can be pretty sure this lump wasn't there at all until today. It seems to be slightly bigger than a marble. I know this isn't super uncommon with rabies vaccines so this could just be a benign reaction, but I'll be taking her to the vet Monday just in case. I just wanted to hear from other people who have had this happen.

I've never had a kitty with this type of reaction, so I'm no help.  Hoping someone comes along with more experience.
 

I have never had this happen either, but have heard that when it does, it can take up to a month to go away, IF it's caused by the vaccine. (unless there is an issue and it causes a sarcoma, which is extremely rare)  But the fact that the shot was given between the shoulder blades rather than on the leg is disturbing.  I would definitely make sure any future vaccine are given in the leg .

that this is nothing and slowly dissipates

Thanks for the positive vibes. When I see the vet monday I'll ask him about why the vaccine was there. Before reading up on this particular case I didn't know it mattered, and upon thinking about I realize he does usually give vaccines in the leg. Just gotta try not to worry too much the rest of the weekend, the kitty is obviously not worried as she's trying to eat my pajama pants right now.

Also, make sure the vet keeps track of the injection sites.  They should be rotated so that the kitty isn't get the same shot in the same place each time.
 

Well, I forgot my vet was closed for the holiday yesterday so I called them this morning. They didn't ask me to bring Maeby in. The vet had me describe the lump and said it sounded like a reaction to the vaccine. She said those usually are nothing to worry about and got away in a few weeks. She just asked us to keep an eye on it and to call back and bring her straight in if it gets bigger or doesn't go away within a month. I had already read as much online, but it is better to hear it straight from your vet.

Good news just for anyone who may have been following this or wants more info if having a similar problem.  The lump is already gone.  I called the vet again to check and he said just to keep an eye on that spot because it would be a concern if it comes back, but that this is generally just a reaction to vaccinations and clears up on its own.  We are a super relieved cat family this weekend.

Hi invadernny !

Well, it's good to hear that it has gone away. But.......do you remember this:

The bigger questions, the ones of greatest concern, have to be

• why was ANY vaccine given in that area?
• exactly which vaccine was it?
• was that vaccine "adjuvanted" - or - "non-adjuvanted"

Before I offer any more, perhaps you can post back and tell us if you questioned the Vet about the "why" part....why was a vaccine given in that location.
