Well, our vet suggested that we give it one more day with the Albon tablets. She said that it takes time for a urinary tract infection to clear up, and as long as he's taking the pills he should be ok. However, she did say she might have to prescribe something stronger. We wanted to bring him in today but she was booked solid, so regardless of how he's acting tonight he's going back in tomorrow, first thing in the morning.
