How long for a cat to recover from anaesthetic?

Hi everyone, I’m desperately searching for some information online.

Just for context, my 7-month-old cat, Shiro, keeps getting bouts of bronchitis. I’ve been at the vet's every fortnight for the last two months.

I’ve consulted several different vets and they’ve all mentioned allergies or even asthma.

He's been on steroids and antibiotics multiple times, but he only gets a brief bit of relief before relapsing.

We’ve also tried homeopathy with no luck.

I live in a flat overlooking a road, so he's an indoor cat, but I do take him out once a day to a local park.

I’ve also invested in a Rowenta air purifier (since his allergies might be environmental).

Today at about 5:30 pm, my cat was put under anaesthetic for a blood test because he wouldn’t let them handle him.

Since getting home at 6:00 pm, he’s just been completely out of it—he isn’t eating, drinking, walking, or sleeping.

His eyes are wide open and he’s propping himself up on his front paws, looking a bit shaky.

I’m really worried about this behaviour. If anyone knows how long the recovery time is after an anaesthetic, I’d really appreciate any info.

Also, if anyone has an allergic or asthmatic cat and has managed to improve their quality of life, I’d love some advice.

Thanks in advance

    Depending on the cat, it can take just a few hours or even a couple of days for some, so there's no need to worry just yet. It’s perfectly normal; he just needs to get it all out of his system. As for the asthma, I used to have a kitty with asthma and I regularly gave her steam inhalations whenever she had a flare-up. I used those large decongestant tablets that you dissolve in very hot water. You just need to boil about a bowl’s worth of water and drop the tablet in, but before that, put your cat in her carrier with the door shut. Put the carrier in the downstairs loo or the bathroom—an enclosed space is best so the steam really works. Place the bowl of boiling water in front of the mesh door, but not too close so she can't reach it or scald herself, and then drape a large bath towel over both the carrier and the bowl to keep the steam in. Leave her in there for 10 to 15 minutes, but no longer, so it doesn't dry out her airways. Repeat this morning and night until she’s feeling better. I wouldn't recommend an electric nebuliser; I invested in one once but it didn’t work very well and it's not practical at all for a cat. Also, since I’m asthmatic myself, I always have some Ventolin on hand—it’s a miracle worker. When she felt like she was struggling to breathe, she’d actually come to me for a quick puff near her nose, which was enough to calm her down instantly. You’d need your vet or GP to prescribe it, which might be a bit of a long shot, but honestly, it’s what helped my cat the most, just like it helps me. Just like humans, cats can have allergies—to pollen, pollution, or anything else. I once knew a cat who was allergic to his owner's hairspray! If you have any more questions, just ask. Thanks for the info. Shiro is a bit more energetic this morning. He's drinking by himself and eating a tiny bit. He's still moving slowly and reacting a bit when I try to get his attention. He's still staring into space for a while at times, and he hasn't slept yet, though. As for the asthma, he’s already having inhalations and is about to start a course of human bronchodilator tablets for his lungs. But the vet is already considering Ventolin. Thanks for your replies.

    Evening. He’s still a bit groggy after the anaesthetic, just like we are when waking up after surgery. It might take him all night to fully come round; he’ll mostly sleep, and he’s likely to be a bit wobbly on his feet if he tries to get up and move around. Give him some water, but don’t worry if he doesn’t want to eat. He should be back to his usual self by tomorrow morning.

    Thanks for the reassuring reply.

    I’m probably worrying a bit too much, it’s just that the vet could have warned me and told me a bit more about what to expect after the anaesthetic. It would have saved me a lot of stress. I’m going to stay right by his side.

    Evening all,

    He’s still a bit groggy after the anaesthesia, just like we are when we wake up after an operation.

    It might take him all night to fully recover; he’ll probably just sleep, and he might be a bit wobbly on his feet if he tries to get up and walk around. Make sure he has some water, but don't worry if he doesn't want any food.

    He should be back to his usual self by tomorrow morning.
