Now I am going to answer my own question.

While I know that One by One should NOT accept this cat, I feel that if we DO take him that it would be worth the risk to have the dental work done with a minimal of tests. Just blood work.

I realize that going the route of the ultrasound would make it much safer for the cat, I would not want to tax our budget for the $300 it would take for an ultrasound on top of the price of the dental work. Not when there are SOOOOOO many more cats counting on that money for survival.

Please post your opinions after you vote. THANKS

(keep in mind, we may not be accepting this cat. There may be no foster home for him to live in.)
