Does anyone know anything about ataxia in cats?

I have taken in three cat siblings with ataxia.

(they had cat flu) that was the trigger

They have already been given Baytril twice, which is actually too strong for kittens, and they already had a fungus.

Two of them have an eye infection.

In little Hermine's case the first vet wanted to remove the eye or grind something down, the second opinion, a very empathetic vet said he would do a cortisone treatment and cut something free when he sterilized her and that he could save the eye 90 percent of the time. She has moderate ataxia on her hind legs and is actually getting along well, but needs to be cleaned every now and then after going to the toilet because she sometimes falls over.

Little Amy had it best, her eyes were both clear and there were no tears now and then she wobbled a little but apart from that you could say she had recovered really well.

But Stephen is really a little worrywart. He has very pronounced ataxia at the back, he can hardly take coordinated steps and at the front he often crosses his arms and practically gets in his own way. Despite physiotherapy and attempts to offer him a wheelchair to make things easier and the edge protection all over the room, he only wants to go where it is absolutely necessary. He has had problems urinating for the last two days. We had the vet look at him and get him vaccinated and he said it could be a bladder infection (they are 15 weeks old) and he said he wanted to keep an eye on it and that he didn't want to give him antibiotics four times straight away. He has a reduced appetite and I don't know if there is anything more I can do for him. This illness is completely new to me. He looks happy when he cuddles and purrs, but he also often looks for peace and quiet. I haven't found a specialist for this area yet. The vet also said it could be that he isn't able to empty his bladder completely.

What kind of tests, help, or medication can I ask for? I got something with magnesium from the first vet, and I'm worried that it could be urinary gravel and that it's the magnesium. The little ones have been living with us for a week and a half now and for the first time they don't have diarrhea, but Stephen has a hint of blood in his urine. I'm really worried about him. The report from the animal shelter said he could die suddenly, and the vet was at our house so he's not under too much stress, but I feel like I'm no further ahead. Today he peed in his bed for the first time and stayed lying there.

I also have three other cats. I've now divided the apartment in half and had the older ones vaccinated because of the cat flu that the animal shelter didn't tell me about. Can they ever be kept together, or is that a big risk for the others? (I've been told they don't have anything contagious.) I have a separate room for each cat to disinfect and separate clothes for caring for the little ones until I can decide.

Thank you in advance 🙂
