Tom is 14 weeks now and his poop has hardened up a little now due to stage 2 milk and now baby rice. It is like really squidgy playdo lol, which is normal i guess but, it is algae green and seriously stinky!! Last time it went like that I had just changed him over to SMA, and it went when i changed him back to cow & gate, but I have not changed anything this time and it has been like that for two weeks, since his jabs i guess. But, he does have antibiotics daily - could they cause it? But if so, why all of a sudden? It is vile smelling! Doc didnt seem concerned.
