well this is griffin's dream noting much yet but the cat (idk if it's how it looks in the book) is suppose to be the same cat griffin turned invisible yes he experimented on it and these kinds of thing were suppose to be bad at this time and yes even today but what otter choice do people at the time have they have too they did not have the same technologies as we do today but later i think the cat was fine actually the cat was going around the room invisible and griffin open the window and the cat left griffin does not know if the cat is alive and assumes it could be dead but i guess if i could remember all he knew is that people try to look for where the sound was coming from
don't take my word for it look it up your self because i don't want to look this up because it puts me so much stress because i don't want to keep questioning everything but i'm sure it what it basically says
idk if the cat shows the part of the eyes that makes it reflective in light but idk but at least it shows where the cat is and also it's a dream anything can happen and gee i wonder who said what the last panel says
