I go through this with Shemp,and Tubby 2.
Tubby 2 was a Porchie,and never had good Litter Box Habits.
Thats why I let him out on demand as its better than him using the clothes.
And if Tubby 2 sprays Shemp will spray too.
A Battle of Dominance maybe thats why both Your Toms spray too.
I wish you Luck with them both.
