Cat fell off balcony.

i was gone out of town for a couple of days and i live in the first floor up, i normally let my cat out in the balcony because he likes setting in the sun, anyways, after i came back home Lucky was gone and the only way he would of got out is to jump out of that balcony, so i looked everywhere for him and posted flyers all around me and this morning and after 3 days of him leaving, someone knocked on my door and they had found Lucky, so i took him in and tried to welcome him back but he was scared to death, so he went hiding and i didnt bother him since i just got him and i can only imagine what he went through, after a while i heard loud noise like if he was stuck somewhere, i ran towards the sound and i found him behind the dryer and poor thing he was jumping repeatedly in the wrong direction like if he was just freaking out so i garbed him and tried to comfort him but he was going crazy and panicking and looked like he was having a seizure, i held him down and kept on petting him untill he got over it, so then i tried to give him food and a bath but he was very scared of me and everything around him, the good news is that he started to eat, so i left him alone once more to calm down and then a few hours later the same thing happened again and i did the same thing again to comfort him but this time i really got worried and each time this happened he would pee himself, so at this point he was just very filthy, so i gently forced him into a quick bath and then after that he was very tired and offered him his favorite food again and he started to eat again then he went to sleep for a lil, and i went on the internet to try to figure out what is causing this, and while i was doing so it happened again, so i took him into the er and they said that he was fine and he just has a bruise on his cheast of lung, perhaps he got hit by somthing while he was gone, but the doctor didnt seem concerned about his seizure and he told me just keep him calm and he'll be ok, while i was leaving, it happened again and they all saw it and freaked out and then the doctor told me that i should leave him so they can monitor him, they gave him a painkiller shot and some sort of antibiotic and sedated him, but no blood work was performed, after i came home i did a good research on this and everyone said that blood work is a must, so im going back tomorrow morning to push them to do that but what blood tests should they do so that i can tell them???? i need help to save my Lucky

thank you very much for your warm response, so here is an update, so i went to pick him up this morning from the er to take him to his vet and they told me that he was fine the whole time but he had another seizure this morning and it was pretty bad and he got aggressive with them and they are saying that rabies is a possibility or a severe head trauma, he wasn't bit by another animal while he was gone, could it be possible that he might have rabies, what do you think? right now he is at his vet for further diagnoses, let me know please what you think about this.

Thanks

Dr. Marie,
you have been great but i have a finale question, im going today to pick him up him up from the vet, just like im very concerned about lucky im also concerned about my health and my family, so my question is, if he has rabies, will giving him all these medications slow down his death or he would have passed by now? i just dont want to leach a monster virus in him that could kill us all, the vet doesnt think its rabies he thinks its a brain damage like you suggested, in other words, if has rabies would he pass away no matter what we are giving him in a matter of 7-10 days or will it slow down his death?? i need advise because im bringing him home today and i want to make sure everyone is safe.

once again i thank you for all your help, Lucky is improving lil by lil, he is eating and drinking and starting to walk better, he is on pheno 16mg that he takes twice a day which have helped a lot with his seizure, the only thing that is concerning me right now is that he is not going to his litter box at all, no sign of pooping anywhere in the house, is that normal?? the first 24 hrs i assumed that since he wasnt eating at the hospital he needs sometime to fill up his billy but its been almost 2 and a half days and he is not pooping, what do you think about that? any signs i should look for? his noose is a lil pale.
Thank you in advance

Dr.Marie
