I have a similar problem where certain neighbors encourage feral cats to populate the area. Human and dog presence does cut down on their entry but they always just seem to adjust their routine. One problem I have with most of the solutions is they cost. It shouldn't cost us anything. Imagine how my cat owning neighbors would complain if I trained my dog to relieve herself in the shrubs around their house. One solution is trapping the cats and turning them over to animal control. Chances are they're not even owned and if they are the owner would have to pay a fine each time to get them out of jail. Last year I have some success with natural barbwire. We have these thorn bushes growing in the woods. I used to attach them to the back fence to keep cats out. Although they still managed to sneak in over places that were not covered. a lot of people don't realize this but cat feces is dangerous to humans and dogs. They eat raw meat(birds, snakes, mice etc)and because of their weak digestive tracks spread deadly bacteria. It's really a public health threat. Unlike a dog where you can see where they went a cat leaves a surprise for later. Any costly solution to me is self defeating. My dog has a standing order to deal with the problem should an intruder be present.

Good luck asking her to keep them home...if it works, please come ask my neighbors to keep their dogs home- they poop in the yard, drag stuff out of its place in the barn, bit my dog and myself.... Anyway- there is a product that you put in the soil- I'm sure someone here will know the name- it is supposed to repel dogs and cats also, I think. I'd hate to use mothballs, as they stink to us and I do not know if mothballs really work. Can you temporarily put rocks/shells- something like that so the cat can't dig in the dirt to 'cover-up'? If it can't 'cover', it might not want to use it as a litterbox??? Spray the cat with a waterhose if you are able to...might make it think twice..

Once the cats come into your garage call animal control and have them picked up and hauled off to the unwanted, unloved cat station where they will be fed, given health care and adopted out if possible. If these are clearly people's pets and you are a super nice person you could post notices warning people their outdoor cats are in violation of your local animal laws (if they are) by being loose and if it continues then they will be picked up and will have to pay a fine to reclaim them. (which is usually the case). I'm of the belief that pets are at risk in the wild urban environment and there is nothing to be ashamed of by calling and having them picked up if they are loose. Also they keep reproducing and becoming pests so it's really not a terrible thing.

A compilation of suggestions from our readers: I've had pretty good luck using bird netting. It's been especially good if I stretch it over a pvc pipe framework (which I spray painted green to be less obvious). I use it over some raised bed planters. I've watched the deer react to it from inside my house. They apparently don't see as well as they hear and smell. They poke their nose into the netting and it startles them and they shy away. Anything protruding through the netting, of course gets trimmed off. It's fairly inexpensive but sort of a nuisance when you want to work in the bed, since you have to roll it back out of the way. It also keeps out the wild turkeys. But the gophers still come in from below. I lost an entire bed of asparagus to gophers after keeping the deer out all season with the netting. I've battled deer forever and these are my tried and true working solutions to the problem....My favorite is grating Ivory soap or Irish Spring all around the items you need to protect. It's good to do this before the deer establish their trails in the very early spring. I also buy small drawstring bags made of a loosely woven material (from a local garden supply store) and fill them with Milorganite (its a fertilizer with an odor that repels deer). I hang these on the bushes and shrubs the deer love to munch! The scent of humans is repulsive to wild animals, or scary as natural enemies, and marking your territory with your scent is a natural deterent. It may be a bit unorthodox to have your husband use the garden as a toilet, but you can accomplish the same thing by soaking rags in a bucket, and then ringing your garden with the rags (using plastic gloves of course) and bury them at the outside rim of your garden with some mulch. Here's something that works great, is cheap and environmentaly safe - Mix one slightly beaten egg with 1 quart of water and spray onto anything that the deer eat. You have to re-apply this about every 4-5 days or after a rain but it really works! We've tried many things - and we have a dog but the eggs work the best. Here's what worked for me: coyote urine. They have all different types of urine drops at Agway (and probably similar stores-find out what the local carnivore is and give it a try. I also sprinkled my stuff with a ton of black and red pepper, garlic and curry powder-nothing went near my tomatoes! Spray with a little water first so it sticks to the leaves and such. You do have to redo it though-every time it rains. I've been trying everything. Here's just a few: 1) Human hair clippings from your local beauty shop sprinkled around the plants. 2) blood meal. 3) Moth ball flakes sprinkled all around. These seem to work but eventually I let any of the treatments lapse and the deer feast. . One year we had a deer problem and after the first feasting in early spring wiping out everything, we lined each bed with chives. It seemed to work and we had flowers the rest of the year, but you have to stay on top of the chives or they can take over the garden.... but when you weed the garden you can just weed out some of the chives as well. (chives bloom adding a nice variation...) Here's my list of plants that deer won't eat: for annuals use:ageratum,snapdragon,salvia,nicotiana,petunia, alyssum,marigold,begonia. Do NOT use impatiens,geraniums,pansies. For perennials, I have excellent luck with these:columbine,coreopsis,foxglove,aconitum,lavender, salvia,nepeta,daffodils,hyacinth,rudbeckia,beebalm,babysbreath.Do not use hosta,daylily,any type of mum or shasta daisy,obedient plant,echinacea. *Note* Any native plants are high risk too, except for the poisonous plants. Deer proof trees and bushes are hard to come by because the ones they don't eat can still be damaged severely by a buck. For evergreens try Spruce,hemlock,Pieris,Leucothoe,and boxwood. Do not use Yew,Arborvitae,pine,rhododendron,and azalea. There are more deer proof plants out there. Actually alot more than people think. I just can't think of them all at this time. Also, plan on using a deer repellant. I use an excellent one called Deer-off. It is completely organic and is comprised of eggs,pepper,and garlic. It is sprayed on the plants and lasts up to 3 months depending on rain and growth rate of the plants. Keep this in mind when it comes to deer: Any plant in the herb family is usually disliked. Any plant that is native is usually eaten with gusto! Any fruiting plant like an apple tree, cherry, or berry bush will be devoured. Hope this will get you started. I deal with deer on a daily basis so I am speaking from experience. I have excellent luck with; Dragons-eye pine, any ornamental grasses, butterfly bush, caryoptoris, anything with really fuzzy leaves, any mints, asiatic lilies, barberry, artimesia, gold thread juniper, trumpet vine, scotch broom, St. Johnswort and contorted hazel. Try Deeroff: Rutgers University ranked deeroff number 1 out of 35 repellents tested. Now labeled for rabbits and squirrels.
