Hey J., I know this is REALLY LATE, but I wanted to answer anyway. I have been panicked several times because my cat(s) hide in my house (3/2/2)......I look under/in/around and will never find them, then suddenly they show up. I didn't know I had that many hiding places.
One writer said something about 'since your cat is microchipped, they'll see it and call you" .... I'm SURE you already know this, but microchips are not visible except with a scanner - they have to be taken to AC or vet or somewhere to scan. For that reason, it is always advisable to keep a collar and tag on your cat. I personally have never found a collar that a cat couldn't get out of. I took a stray to the vet one time to have his shots and neutered (he wasn't mine, but I figured as long as he was showing up regularly for meals, he was sort of part-mine). I had them put a harness on him with the rabies tag because I never had luck with collars. Well, he stuck around for a few days, then left. About 2 weeks later, here he comes with his rabies tag gone, the harness hanging on around the neck and one leg. I was trying to get it back on him and he took off. It was a long time before he'd even come close enough to let me pet him, but I didn't care - at least he wasn't out breeding!
I also have a cat that darted out the door every time it was opened - no matter how careful I was. Her mother was a stray who didn't bring her kittens up until they were about 10 weeks old - her and her brother. I finally got hold of all 3 of them, got them to the vet, shots, spay/neuter. About a month later, mama starts wandering a few days at a time, then longer, then one day she just didn't come back. The male kitten starts wandering - he'd be gone all week, show up on Friday afternoon, stay all w/e, play with his sister, then disappear on Monday until the next Friday. This went on for months. Then one day, HE didn't come back. This was in the dead of winter. Little Socks cried and cried for her brother. She wouldn't sleep in the area I prepared for them outside with a heating pad. So I trapped her and brought her inside....We had an OLD kitty inside that would groom her. She seemed content, then started darting outside again. (For the record - we live in the country - it's a prime location for people to dump animals, so this is something we contend with every day.... most of the time it's cats, but we've had a few dogs too). Anyway, she started losing her hair. I got her to the vet, he says she has allergies, so he gives her an allergy shot, says keep her in for a couple of weeks. I did, she got better, hair started coming back.....she gets out again .... same thing happened. So I make her stay in and have gone to great lengths to make sure she stays away from the door! Her hair has grown back in and she's beautiful - again - it's not worth it to me to have to take her to the vet every month for allergy shots. We had another stray in the house and they became best buds....we had to have our OLD one put to sleep....that was sad - nearly 18 years old, but Socks and Shiloh are doing great - totally inside kitties.
That's the only way to keep them really safe. It's a pain to have litter boxes, but I'd rather do that than wonder if they're OK.
Right now, we have about 13 feral/stray - we've made shelter for them under our porch with dog houses and heat lamps and rugs. They've all been spayed/neutered/had shots (except for the 2 newcomers-both males).
Like my sweetie says, 'if you're going to feed and care for strays - there's no guarantee they'll stay safe ... they might go somewhere else' .... I know that's true - we've had a couple get hit by idiots driving 70 mph down a country road (ARCGHHHHHH). It's heartbreaking, but .....
I even took one to my vet and had him neutered/all shots, etc. He'd been showing up at my place for weeks (all the strays were in heat so I had a ton of toms)....but Dexter was sweet/tame and I could pet him - most of them are not. I found out that Dexter aka Mr. Pickles actually belonged to some neighbors a few lots down. He showed up with a collar the day I was going to take him in....I wrote a note and taped it around the collar. A week later I got a call from his owners. I explained that he'd been hanging around - pretty beat up looking, gash in his head, abscess on tail - fighting - and I asked them if he'd had any vetting....of course he hadn't - he'd shown up as a kitten on their porch a couple years earlier....they fed him, etc. Well, I told them I was going to take him for shots and neutering and I hope they didn't mind.....(actually, I didn't care of they minded or not - if he eats at my house and hangs around, then he's fair game! LOL) They were fine with it. Sometimes if I don't see him for a few days, I'll call them to see if he's there and vice versa. Sometimes they keep him inside. But he always shows up. In fact I have a duplicate of him - JJ (his son). But I finally trapped all the mamas and babies and toms and fixed 'em. We just don't need any more pets!
I DID learn some valuable information from my vet: Female cats are in heat and pretty much ready to breed continually from early February through late October, so that's when the toms are out & about....AND, the females will breed again when their kittens are just a couple weeks old, still nursing!
Oh - another thing - most vets won't spay kittens before 6 months. I was told they don't start breeding until about 7 or 8 months. Well, guess what? Yep, JJ's sister, Gum Drop was 5 months old and already pregnant....just barely, but definitely pregnant. We went ahead and spayed her. So, if your vet won't do it, take them to the Humane Society or find a vet who WILL.
Sorry for the long post .... birth control in dogs and cats - it's my passion.
Thanks for listening! Too bad we can't post pictures!
Glad your baby came home!
