Hello, and welcome!
My name is ***** ***** I will be glad to be of help to you and Busta.
My apologies that you did not receive an earlier answer. Various experts are online at different times and I recently logged in and read your question. Your patience is truly appreciated!
I'm sorry he's not feeling like himself after his plane ride.
Did he travel in a carrier, in the cabin, with someone you knew or did he travel in 'cargo?'
Was he given any sedation before the trip?
It sounds like he was distressed about the whole experience of flying and he also missed you and is feeling stressed, now. When a cat isolates/hides, he's not feeling well. A good product to relieve stress is Feliway; this comes in a spray and a plug in diffuser and it emits calming pheromones. You can find it in pet supply stores and online. Here is more information: FELIWAY
The not eating/drinking is very dangerous for his health, so try to dropper feed him watered down paté (smooth) style canned cat food or plain, jarred baby food chicken containing NO onion or garlic--Beechnut Stage 1 is a good one. You can also dropper feed him water mixed half and half with children's unflavored, clear Pedialyte, so he does not get dehydrated. He might be dehydrated now, and a good test for this is to pick up the skin/fur on the back of his neck with your thumb and forefinger; if it returns to position right away, that's fine; if it takes a few seconds to go down, he's slightly dehydrated; if it 'tents' and doesn't return down at all, he's severely dehydrated and needs a vet's attention, immediately.
Not eating, even for a short period of time, can cause a serious liver condition in cats, called hepatic lipidosis or 'fatty liver.'
The way you described his walk could have several meanings. If he was confined to the carrier and was laying down the entire time, when he made the plane trip, his muscles and ligaments might have stiffened up and his back may be sore. You can try to massage his hind legs, if this doesn't hurt him.
Due to all his symptoms, it would be advisable to have him seen in person by the vet, as soon as possible, so you can get a definite diagnosis and treatment. If he's dehydrated, he will need fluids I.V. or under the skin (subcutaneously or sub-Q).
Since he urinated last night, that's great, but if he has not voided at all today, it could be because he's not really taken anything in, but there might also be a possibility of a urethral blockage, which is a medical emergency in male cats. Here is more information:
I hope all will be well with Busta and please let me know how he's doing and what the vet tells you. Thanks!
Please be so kind as to rate my answer with positive feedback, as that is the only way I receive recognition from the site for my assistance. Thank you very much!
