Unsuitable grain size
For cats with dental problems, or missing molars/teeth, I don't recommend these—they're disproportionately large and the shape is unsuitable, kind of pyramid-like... and honestly, not great for cats in general! I don't know if you'll publish this, since you reserve the right to choose what gets posted or not, which is pretty subjective, but I think it's only fair that, given how expensive they are, people should be informed before buying! My tomcat can't manage to eat them.
