Thank you very much for your question.
To answer your question simply and directly your pet needs to be taken to the vet ASAP. I advise of a 12 hour window is get the needed injection before irreparable harm is done.
Any contact be it a bite puncture or scratch can and will cause a blood infection and death should the animal not be treated with antibiotics. There is an irritant in the cats saliva that causes the bird to become immobilized. If the scratch or bite is slight it could show as late as a few days from now. It would be impossible for you to be able to guarantee that the bird was not scratched or bit in any capacity due to feather coverage and its not worth risking the life of your pet.
For the evening keep the bird warm and in its cage covered to try and make it comfortable as im sure the excitement was too much for the little guy. It will be a simple procedure at the vet...with the administering of a shot. Im sure after that your pet will enjoy life throughout our new year and beyond.
Sorry if this message seems scary, but must people dont understand the dangers associated with even the slightest wound from a cat.
