A stray pregnant cat is visiting us for food, recently I noticed that when she wants to eat she hiss to the food and stop eating. at first I thought maybe she has some bone or something stock to her teeth (because it happened to my other cat once), so after examining her mouth with a lot of difficulties that was not the case. also her mouth stinks which obviously is a sign of infection.
It's so painful watching her eating something even though I chop or mix the food so it don't need chewing...
So here's the situation;
She's pregnant (I guess she has 1-2 weeks to give birth) and semi-wild with an infected tooth.
I'm living in Iran and vets here only do vaccination, they're no dentist. that aside Iran like any other country is in quarantine, only food and drug stores are open...
From my previous experience I know that for cat infections vets here prescribe si-fixim dry syrup 1 ml every 12 hours but since she's pregnant I'm not sure about giving her antibiotic. as long as she has that rotten tooth in her mouth it's going to get infected again too...
She's in pain and I'm desperate, what do I do?
