I rescued a small BTA not long ago and,now it keeps splitting.Agood thing but what is the norm.The 2 years my friend had it .It never even really inflated.Yesterday .When I woke up ,I had 2 BTA's.By 5:30pm I had 4 BTA's.Now 2 of those look like there about to pull apart.I dont think this is norm?Will they stop soon?
