In 2020, Elena noticed that Klaus got tired very quickly and that he was breathing too fast. "At first we just thought it was because he is still little and loves to play so much and that he is doing well..." But as it became more frequent, Elena started to get worried, so she made an appointment at the vet to check his blood, lungs, heart and other organs because they didn't know what the problem was.
After the vet visit, he was diagnosed with cat asthma and severe allergies. Unfortunately, their vet said cats can never really cure asthma... "But we love Klaus so much, he is part of our family so we are doing everything we can to improve his life. Among other things, through homeopathic herbal medicine and by taking good care of him, that way he still has a peaceful and happy life!"
At the beginning, it was very difficult to deal with Klaus' asthma because they were still very much searching for which medicine would be best for Klaus. The diagnosis and its consequences drastically affected both Klaus' and Elena's lives. But Elena mentioned that mostly Klaus’ live, as he was still so small and had epileptic seizures every week, sometimes several times a week, which were very stressful for him. For Elena, this was terrible to watch, she quit her job at the time, because she had to take Klaus to the vet almost every day for check-ups and to make sure he was breathing properly. "I was out of work for more than six months because of this to take care of Klaus at home and further study asthma in cats."
