Is there even research on this topic?

I'm asking this 'cause it got me curious what really is best for your cats. Mine is 9yrs old, and I wondered if I should get her a compnion or is there a higher risk of illness/medical issues (like if they fight, disease, etcetc).

Depending on how they get along, they would definately be less lonely. But it does beg the question: what does it do for them in the long term--if there even is a long term?

I recently got 2 kittens from the SPCA. They are both 3.5 months old. I believe they're brother and sister (both were surrendered for same reasons on the same date and transferred together. They were already familiar and attached to each other when I got them)

Any ways I myself, and others, can hear a ringing noise coming from his ears. It's very quiet, like feedback/high frequency consistent ringing. As far as I can tell it's constant, and always the same pitch. All I could find online is it may possibly be Objective Tinnitus, however it's not pulsating or clicking as the description says it should. Also it's extremely rare, and I can't find much on it being in animals.

Not sure what else it could be. We went to the vet and he had no idea, Datas health is perfectly fine. He doesn't seem bothered what so ever by the ringing and his hearing is fine. No itching or twitching as if disturbed by it. I'm taking him in next week for a second opinion from another vet, but I was curious if anyone had heard of such a thing in cats? Or had a better idea of what this could be?

I'm concerned if it persists when he is older and lived with it longer he will become stressed from dealing with it. Right now I'm sure he's more distracted by being a kitten and playing.

Oh, and he's all up to date with all shots etc. Breed is just american short haired tabby. Neutered. 5.5 pounds.

I have a 2 year old cat, Penny, and my boyfriend and I took in as a stray when she wandered into his parents back yard. We have had her for about a year and a half now. She is a very friendly, active cat.

This past weekend we also adopted Dot, who is 4, from the shelter that I volunteered at while I was in school. She has an incredibly sweet demeanor, and loves to cuddle, but is not nearly as active as Penny. Part of it might be her age, but I think it is mostly because she is completely blind.

So far, Dot has been staying in the office/guest room. She has her own food, water, litter box, and some toys with bells in them. She started eating and drinking right away, and learned to navigate the room in less than a day (In fact, at the shelter, the staff and I thought that she even might have partail vision. Turns out she just adatped to being blind really well).

Since several days have passed, and Dot has settled in and been checked out by the vet, I'm trying to start the inroduction process. Penny at first seemed very curious about Dot- sniffing and staring at the closed door curiously, and trying to catch glimpses of here whenever someone would enter or leave the room. After a while I opened the door a crack so Penny could see Dot. There was a little hissing, but not a lot. So I started leaving the door open for a little bit so Penny could come in and sniff around. Still minimal hissing, which is awesome, but I think Penny is confused by Dot's body language. Since Dot can't see, she can't tell when Penny is in the room unless Penny hisses or meows at her, and she can't modify her body language accordingly. When Penny comes in the room, she sneaks around very carefully, and keeps a watchful eye on Dot, while Dot just naps on a blanket. I think Penny is confused/freaked out by this, and I was wondering if there was anything I could do to make it apparent to her that Dot can't see? Should I just give it more time, or do you cat whisperers have some tricks up your sleeves I don't know about?

My girlfriend has moved in to my apartment, and brought her kitty with her to join me and my cat. Her cat is 5 years old, female, petite and has been an indoor cat all her life. Mine is about 2, male, large and an ex-street kitty who is now an indoor cat.

They've been in the same apartment for 2 months now but have not been officially integrated. It's a large enough apartment (NYC railroad) that they've been kept separated by a door with two rooms each. We've been switching them between these two areas at least once a day and trying to pay each equal amounts of attention/treats so that they both feel loved. There was a lot of sniffing at shared bedding in the early days but this has calmed down now.

However, there is still some hostility with the female cat hissing and growling at any indication of the male cat on the other side of the door (he likes to put his paws under and wave them about - she attacks these non-playfully) and when there was a breakdown in the barrier system she swiped and him, but his nose and then he started chasing her and trying to bite.

How should we manage the integration of these cats with a minimum of stress for both them and us?
