My boy is a mini lop too LizziAnn and he was neutered when he was around 5/6 months old weighing 2 kilo’s. My boy was a sprayer too – until this time I never thought about getting him neutered, but once I realised this could be the solution I had him booked in quick smart! And I have never looked back – bloody brilliant!!! Stupidly, we still let Henry in our room and tolerated his spraying till his op – our walls, furniture, the dog’s were already covered in bunny pee, so except for us and our bedding it didn’t make much difference (and for as gross as that sounds, I promise you I am a clean person, he he hehe). So when he went to the vets, I didn’t worry about him once! I was kept busy scrubbing and cleaning everything in my bedroom (including my dog’s, ha ha ha!) and when he came home everything was clean and fresh again – just wonderful!
In the meantime, I 3rd Silverpaws suggestion – fantastic idea! Cheers.
