Here's an update on Biscotte.
I took my Lili to be PTS on Saturday, and since Biscotte has huge teeth issues + had broken her two front teeth, I took her along to ask the vet to do just a quick trim as I have an appointment for the whole teeth issue today. In order to give us more time with Lili, she took Biscotte in the back first and trimmed her teeth. I knew they had to put her in the oxygen tank as it was taking so long... then the vet brought her and we proceeded with Lili's PTS
Once the vet told us Lili was gone, BF, who was staring at the travel cage, looked at me and said: Biscotte is not well. She was having a hard time breathing again, so I asked the vet if they could put her in the oxygen tank once more. She was supposed to stay in for 10 minutes, but I only got her back after I requested her about 30 minutes later, in a much better shape, still panting, but breathing. I also got her prescription changed from Zithro + Doxy to Zithro + Baytril, as I wanted. But the nightmare was not over yet. Between 4:00 and 8:00 pm on Saturday, I had to steam her 3 times. The last time, she would sneeze but wouldn't disloged anything, and her breathing was very... caverny (don't know how to describe it). She just kept getting worst, so I panicked and decided to go straight to last resort and use Ventolin. I used Hopefloats' TP trick and pumped her. After about 2 minutes and a lot of sneezing, she started to breathe normally (abdominally) again.
On Sunday, she was a bit noisy, but I decided to let her be and see what would happen. She was "fine" until about 6:00 pm, when it all started again, all of a sudden. I rushed her in the bathroom for steam, which of course didn't help, screamed at the boyfriend for coffee, but as it wasn't coming fast enough I rushed her into the office for more Ventolin - which did the trick again. I begged her to keep fighting until the new combo could kick in and maybe give her another chance... but honestly, at this point, I was a wreck and hated myself for not letting her go with Lili the day before.
Yesterday, I came home to a silent cage. Biscotte was resting in a hammock with her sister, no sound. No crisis at all the whole evening. She was active, she was hungry, she was alert... she was back! Against all odds, I believe the combo kicked in and is helping her. I do not scream victory yet - to be honest, I do not think I will up until she passes, this was too horrible an experience - but I have a fair amount of hope that she'll pull through. I hear some kind of a liquid sound when she breathes, but it doesn't sound like it's coming from her lungs... of course, I will have the vet confirm tonight.
Thank you all for your help and support, she wouldn't be where she is today if it were not for your advices, support and ideas :hugs:
