Yes I have read about the sunflower seeds.
The first bag of bird seed I had was a mix which included some sunflower seeds in them. It was a pain in the butt to take out (I admit I was lazy :mrgreen: ) but I took out a good majority.
If I took pictures of my current substrate, you wouldn't see any sunflower seeds but its not because I think they are dangerous, its just because they are kind of an inconvenience.
He was housed with the sunflower seeds for about 3 months or so and he never ever even looked at one as food. And yes I checked his poo and never saw any sunflower shells.
Calcifer eats a lot of the seeds. I will often hear a crunch when he is hiding in his little cave (home made of food, thats the life) and his poo is always filled with seeds. ..........Which kinda leads me to wonder if he is even digesting them since they are passing through and still recognizable as a seed.
Have you noticed seeds in Gualams poo?
