sorry for spoling the fun, but if u click on MRI machine it says something that its Exam machine just the thing u could find ur rat from.
There are 2 things to use blood and mri Blood has brown oe white chicken and dog (ive collected 2 dogs from bloodwork so i know)
Then there are MRI which have that other colo chicken white or brown and i assume that rat is from MRI then just way more harder to get the nchickens =)
