i have had my ball for about 3 months now and i have started to notice him squeaking a little bit. he did it at first but that was because he was getting crap in his nose. but now. he is doing it again all of the sudden. i have done a lot of research about it and everything points to an RI, however, he has no other symptoms, none. no funky bubbles or cream cheese mouth. nothing. he is active and fat and happy but he just squeaks every once in a while.. is it normal?
