I sure wish I could reach through the computer and examine your cat!
What you are describing suggests to me that he may have some back pain or pelvic pain. Cats can have back pain due to a “slipped disc” though that is not very common. I see it about 1000 times more often in dogs.
Instead, with what you are describing, I am very worried that your boy may have a fractured pelvis.
Cats with a fractured pelvis often move very gingerly, holding themselves low to the floor and preferring to stay close to walls for support. A fractured pelvis can cause a lot of internal bleeding as their are many blood vessels in the area. This internal bleeding can lead to shock, which can be life threatening.
Unfortunately, there are no pain killers that you might have in your medicine cabinet that would be safe to give to a cat. Tylenol is very toxic to cats! And ibuprofen and aspirin are also toxic to them.
Here is more about these drugs:
With a fractured pelvis, there can also be a tail injury. There may be nerve damage which can affect the cat's ability to urinate. This would need to be assessed by a veterinarian.
I really am very concerned that this is what is wrong with your boy from your description.
More information on pelvic fractures:
and information on tail injuries:
Unfortunately, I have seen this type of injury many times with cats that have been hit by a car, though it could happen with a fall, or if he were kicked by a large animal.
With a fractured spine or pelvis, there can also be a tail injury. There may be nerve damage which can affect the cat's ability to urinate.
I have seen indoor only cats with pelvic fractures from falling. It is a very common fracture, and tends to happen if the cat falls in a "sit pretty" position. For example, I have seen it when a cat has jumped onto a table with a tablecloth on it, and has slid backwards off the table (on the cloth) and falled directly onto the pelvis.
The good news is that in cats, pelvic fractures very often heal without surgery as long as they are not through the hip joint (acetabulum). It does require 8 weeks of STRICT rest in order for healing to occur. Strict rest means that the cat needs to be confined to a large dog kennel with food, water and litter tray in there. The cat should not jump AT ALL for 8 weeks and should minimize walking so that the bones can heal.
I would definitely recommend that you have your cat checked by your vet immediately to see if this is what is going on with him. His elevated respiratory rate and temperature make me very worried about him!
Your vet may want to take an x-ray, but if this is an uncomplicated pelvic fracture, then 8 weeks of rest is all that is usually needed for recovery!
I do hope that this helps you to help your cat!
