sorry for the stupid question, but what is "the former" and what is "the latter"?

Did you mean I acknowledge the sentience of plants but not animals?

I believe that all life might be conscious, but life that is "very different" from me I have a hard time imagining what that consciousness might be like. For animals, especially mammals, I can easily imagine what they must be feeling and empathize with them. I can understand that a cow feels pain when hurt, because the cow is very similar to me. A plant might also feel pain when hurt (even the grass I step on might not appreciate me walking on it), but I'd have a harder time empathizing with that.
