Cats are now universally recognised as the gardener's public enemy No.1.
I & my wife love our garden & try to keep it in good condition .... growing flowers/vegetables .... a nice lawn .... & enjoying BBQ's, throughout summer.
The only thing that spoils our *private* walled garden are the local vermin, aka CATS !
Up until a couple of days ago, we were having to dig up & bin (OUR dustbin) fresh cat shit EVERY morning, from our garden ...... & we have NO pets.
Cat owners will speak in defence of their vermin ... but MUST realise what VERY selfish people they are.
The garden is OURS ! The cat owner's shitting machine is theirs ! They make ZERO attempts to control their straying vermin. Admittedly, I thank the VERY rare cat owner that takes the trouble to keep a litter-tray on their own premises. THANK YOU !
Let me explain. Dear cat owner, would it be OK if I came into your garden & had a shit in it EVERYDAY ? How would you feel about having to clean it up , EVERYDAY ?
The vast majority of cat owners are LAZY , selfish people. Cat owners do not have to take their pets for walks ..... unlike dog owners.
Cats ALWAYS shit outside of their owners premises.
Cats are smart ... but also VERY demonic & selfish. How many other animals "kill for fun" ? ( some smart b*stards might say "humans" .... but, tough titty, reader .... I'm Anti-Hunting"). I wish I had a quid for every time I've seen a cat kill a little bird & then play with it's mutilated body ...... just for playsake ..... not even bothering to eat the corpse.
Cats will go to ANYONE that offers them food. ZERO loyalty, unlike dogs. Women & homosexuals love cats. "Furry, lovely, cute creatures". But, cat owner, watch your cute, furry little pet walk up to & press it's body (whilst turning on the EXTRA loud purring !) to your worst enemy of a neighbour, simply because they held out an outstretched hand (as in offering food) & then made the right "pss pss" noise. Cats are traitors, unlike dogs.
To get to the point, there IS a way of keeping them out of your beloved garden.
Cover all access walls with non-drying, black, anti-vandal paint. ( "TORA" is a good, UK brand) Coat the tops of the walls to around a quarter of an inch deep. It's not very expensive & most paint retailers stock it. Cats are very vain creatures & this stuff is a perfect deterrent to the little monstors. It's like crude oil on their paws ...... they WON'T come back. It also, hopefully, gives their selfish owners something to think about ...... as the oil based substance is brought back into THEIR homes ( & hopefully onto their carpets !).
Cocoa mulch is a good cat poisoner. Downside ..... a little expensive (large amounts) & not very attractive in the garden.
Most important to remember. The cat, like a burglar, is an unwanted intruder. Therefore ..... legally ..... anything that you mix with cat-food & leave on a plate ( on YOUR cat-shit-affected area ) is up to you.
Warfarin & finely grated, broken glass are good ideas.
Happy vermin eradicating !
