as you may know i had 4 foster babies. i kept two and my mom took the other two. Everyone had thier first FVRCP and when one of my moms little guys, Squeekers, had his second booster on tuesday, along with his second FIV booster (she has a FIV+ cat) he was very lethargic and feverish within 4 hours after. she called and we both thought it might just be a mild reaction and he'd be fine in the morning. well by the next morning, wednesday, my mom had to rush him to the vet, his temp was 105 (according to the vet) he wasnt eating and was extremely lethargic and shaking due to pain said the vet. he was kept there on pain meds and IV fluids steriods and antibiotics. finally his fever broke last night but went up a little to 103.4 this morning but dropped a short while later and stayed stable. he was released tonight with Zythromax antibiotic for home and to take his temp and keep an eye on him. he is almost back to his normal crazy energetic kitten self. I was wondering if there is anyone else out there that has expierenced this type of reaction in their cat. also i thought it couldve been because their momma cat died when they were 3-4 weeks old and i fostered them. on a side note the vet worked vey well with us, they were wonderful, they contacted the vax company and there were no other reactions reported and did request the rest of the batch that our vet had used on Squeekers. they let us visit him whenever we wanted and didnt make us pay a cent for anything they said they'd bill the vax company. the vet is also very hesitant on vaxing them for anythig other than rabies now,and only the rabies under close supervision. i would like to hear if and one hs ever seen or heard of this type of reaction, no vomit no diareha (spell?) no uticaria. thanks again.
