<human>: So, tomorrow I am flying to Germany with my 2yo tabby.

She is very well-behaved at home, however once she is in a crate she starts howling and meowing non-stop. I really don't want the passengers to get tired of my motherfucking cat on the motherfucking plane, so I've anticipated using a sedative.

However, today I took her to get her health certificate and asked the vet about a sedative for the long flight. She told me it is dangerous and not recommended, and now I'm worried for my cat's comfort.

She recommended benadryl, but said it could be hit or miss. 

I plan to arrive at the airport and give her a half of a benadryl (she's 9lbs) and then we will fly for one hour to our next stop. I can see how she behaves for this hour to see if she should be sedated with the other pill for the next flight (like 8+ hours more non-stop).

She will be flying under my seat.

The vet told me "if she has a reaction, they're not going to stop the plane for her." And it just got me really worried. She has been neutered, so I imagine she has been sedated before without problems.

The pill she gave me is called Acepromazine Maleate tablets 10mg(cut in half)

Provide a brief overview of the text.
<bot>: flying USA to Europe with cat under my plane seat. Cat meows a lot. Not sure if she reacts to sedatives. Anyone with experience?
