What size pebbles do I need to avoid cats toilet. Please help.

[Eaney]

I'm thinking of putting down some pebbles in my garden and was wondering what size I need to get to avoid the local cats using them as a toilet.

Anyone know?

How about using citron peel ? Works a treat or pepper ?

Hm - no guarantees - our pebbles are quite big but next-door's cats crapped there once or twice having strolled in expecting their usual toilet facilities and been caught short.

However, having said that, ours are grape-sized and usually clean. (I think pea-sized are dodgy.) HTH

pea-size are def a big no no! We have them and the neighbourhood cats use the front of our house as a cat litter.
