hi. my baby is 9 years old and went to get his rabies vaccine yesterday. he also had a regular checkup and his glands were released, all normal. this morning i noticed he was acting a little weird, sitting in places he doesnt normally, and kinda blanking out. i didnt think too much of it at first. he has been uninterested in food all day. when i got home around 9pm, i could tell something was really wrong. he looked uncomfortable (laying in a loaf which he never does), seemed uninterested in being touched, and still wouldnt eat. i offered him his favorite food thinking he was just being picky (cat soup), which he normally licks clean within 1 minute. he lapped it occasionally for a few minutes, and then walked away with it 3/4 full. this has never ever happened, he loves his soup. he then went to loaf in his normal spot, but he wouldnt lay down and wouldnt get comfortable. i brought him to his safe space under my bed and hes now just laying quietly now. im really worried about him, he is acting very strange, lethargic, and has no appetite. google says this can happen after a rabies vaccine, but is rare. hes never had a reaction to a vaccine before, but we went to a new vet this time so maybe it was a different brand? if he is still acting this way in the morning i will call the vet and take him in for an emergency appointment if necessary. in the mean time, is there anything i can do to keep him comfortable? i sat his favorite toy in his bed with him. im thinking of bringing him some water. google also said the symptoms could be related to liver or kidney issues, which is how my last kitty passed at 16 years old, so im very worried it might be the same. i know its a common issue in older cats. any advice on how to make him more comfortable at this time? thank you so much in advance.
