Albus has had one health issue after another since his neuter a couple of months ago. First he had a mild respiratory infection and swollen gland on his neck which was taken care of with antibiotics. Shortly after, he developed a large abscess which was lanced and is almost done healing. But yesterday I noticed when I got him out to clean his abscess that he is falling all over the place. Is this something completely unrelated or a possible sign that the infection from his abscess went systemic? He was perfectly fine on friday, he can still eat, drink walk and jump but his movements are clumsy at best and he'll occasionally just fall over on his side.
