Roo's loosing weight 3 weeks ago he was just over 800g and is now just below 750g he is looking quite slim but not boney yet, hes had two dentals in 4 weeks and seems to be choking on his food and water all the time, is there anything i can do to help him put on weight I'm already seringe feeding him but he lets me know when hes had enough when he starts spitting it out the other side of his mouth
