I have never noticed any difference either, but it does make sense that Brodie may be "maturing" faster because I know that Tom cat pee stinks!!

Mine are getting neutered on Tuesday so hope this solves prevents any problems for Both of us. I notice that Robbie seems to have his equipment! My vet does not neuter before 6 months as he claims it is more risky - though I well know that many vets do. Maybe it is just more complicated so he does not do it..... Oh well - it will be done soon!!
