Taking the cat to the vet is always a potentially dangerous adventure. This poor cat is getting its teeth done and will, hopefully, be happy with the results.
my poor little lady Violet Elizabeth Bott only has two teeth left all the rest at different times have been removed by the vet, she is 12 yrs old bless her and we have to chop her food and put water on her senior biscuits to soften them . now known as "the two teeth terror".
Hope all goes well.
