Is this ordinary for cats?
I have two cats, Aurin and Dydimus. Aurin has 4 incisors total. 1 incisor on the top left, 1 on the top right, 1 on the bottom moved out and 1 on the bottom right; however Dydimus has 6! 2 on the top right, 2 on the top left, one of the bottom right and one of the bottom left. Is this common?
Sure it is normal... They're still kittens, so you will see more teeth come in as they catch to be adults.
And Very cool names...
yes its normal. sounds resembling a healthy and strong male cat to me...my cat Vash has those and it be really surprising opening up his mouth and finding extra teeth...as long as it doesnt hurt them in besides its normal.
Answers: young kitties do loose their "kitten teeth" and sometimes the new ones come contained by before the old ones fall out.
whether they don't seem to be bothering him you can wait it out, but if he is paw at his teeth, you should probably see a vet sooner rather than later because they might be impacted and cause problems.
and whether they aren't young kittens (6-9 months of age) then they should see a vet.
