My cat was diagnosed with Pyothorax almost a month ago. He has been on antibiotic for about 4 weeks and has been doing better. I recently got a new cat and I wanna know is it possible for my cat to give this new cat pyothorax?? Is it contagious to other cats?? They sometimes eat/drink out of the same dish even though they have there own dishes. I just don't wanna have two cats with pyothorax. Please answer my questions ASAP!!
