Error: With Starting Episode Oggy's Tails Is White No't Light Blue
Error: When Oggy got into his bedroom during the night scene, he took off his foot wears but when he got out of the house in order to scream, his foot wears are on him again.
Error: When Stanley passes out after smelling Oggy's foot, he falls on his back, but in the next shot he is lying on his stomach.
The scene where Oggy ran out of the house and scream resembles from Tom And Jerry. When Tom accidentally stepped on the tacks, he got out of the castle and scream.
However, Oggy had screamed due to being frightened of Stanley while Tom had screamed due to pain which Jerry and Nibbles made.
It's impossible for Oggy to be scared of mice, since he is a cat and cats choose mice as their own food.
It might be known that Oggy resembles Tom's cousin, since they both are afraid of mice, but Tom's cousin suddenly is not afraid of Jerry anymore when scaring him as 'Two-Headed Tom'.
It's seems that Oggy does not seems to be scared of Stanley when they both are sharing a bed in the emergency room before Jack came in, implying that he had enough of being frighten of mice or the poisoning smell caused him to change before he woke up.
