Today Henry has been unusually pesky about going outside and I have watched him and he is straining to pee. He peed in the house which is not normal and he wants to go out every 15-20 mins. I went out with him and watched the poor guy strain 3 times with no urine coming out. I am not sure if it is a UTI, that's my first guess. But, it is also VERY windy here today and it's REALLY loud and making tons of noises so I am also wondering if he could be stressed. I am going to have ot watch him for the rest of the night and tomorrow call the vet, if they are open since it's a holiday. I didn't see any blood in the urine that I cleaned up when he peed in the house. Any suggestions?
