I agree with Ivy that mainland is best for cats, but like Lucky I have also encountered issues with inconsiderate neighbours. There is a land rental guy on the sim I am on and while he and his operations are fine occasionally his tenants cause problems (usually encroachment over my border), that said I don't think he places restrictions on breedables so might be worth a look, its the parcel right next door to my cattery and you can TP there from my picks if you are interested in looking. Its usually Estate rentals with restrictions rather than mainland ones I think. The landlord are the ones getting moaned at on Estates but mainland rentals seem to be slightly more relaxed. Anyway, he has a booth with his rentals on the plot next to me. There are horses on one of the rentals and a lot of them, I rarely have any issues with my cats here. Hope that helps
