Have Cat Questions? Ask a Cat Vet Online.
Hello this is Dr. Holloway but you can call me Dr. H, and I am a licensed veterinarian. I understand that you are concerned your vet didn't give your cat the FeLV vaccine and wanted to know if re-dosing him would cause harm.
Generally speaking giving a pet double vaccines won't harm them in most cases, and at the most you will only increase the chances of causing a vaccine reaction (which mind you are more rare in cats than dogs). Although, I would still try to wait at least 2-4 weeks before considering having the vaccine given, just to give the body time to recover in case it was indeed given.
Also I would also ask the vet for your cats records. Often-times the label that was on the vaccine bottle will be on the file. This is proof that the vaccine was given, because the vet will inject your cat, then pull off the label that was on the syringe and place it in your pets records. Also unless this vet is extremely absent minded, I would trust that the vet did what they said. Another thing to consider her is that we usually don't drench the pets skin with alcohol when giving a vaccine, so you won't see any wetness on the skin at all. Sometimes you can also feel a lump in the area where the vaccine was given.
Let me know if you have anything further you would like to discuss
