Hello
Its been a big while since I have posted…..but I need help 
Long story short…..Our Howey died a year ago :'( leaving our sweet matilda on her own. We now have a french lop called Archibald to bond with her…they do not get on yet but we are working on it (that isn’t my problem)
So my issue….
He stinks! His wee smells of very strong ammonia, we are scooping out his tray everyday and as soon as he is back in, it stinks again! We dont have this problem with matilda at all. He has been neutered for about 6 months now too! (he is 10months old)
Is it because he is bigger?? Howey never smelt like this so it cant be because he is a boy……can it?
I have changed litter from paperbased to megazorb….got some powder stuff that you sprinkle in the litter (rabbit safe of course) Is there anything else I can do? I come home from work and am greeted with this strong unpleasant smell 
Do any of you with the larger bun have these issues?
