I would definitely talk with your vet. It's possible he's already been neutered or perhaps his testicles haven't descended. He does look neutered to me, though, but I am not a professional.
My vet has stated previously that cats are not like dogs. Dogs will bite at fleas and not get them, but cats will get almost all of them, so she always recommends deworming for tapeworms if your kitty has fleas.
My gray kitty that I've had since she was 6 months old also has a few white hairs on her back. I think it's normal and not because of any trauma or anything. Even my tabby boy has a few white hairs along his back.
For the first time since we've been caring for him, our outdoor community kitty has fleas. He's been so itchy and scratchy the past week to 10 days. I was thinking it was food related since we changed food about 3-4 weeks ago, but then I saw a flea crawling on him. I got topical flea meds from...
When my boy gets runny poops, we give him human Culturelle, about 1/4 of a capsule mixed with his wet food twice a day. You can also give saccharomyces boulardii. Feline Gut Soothe or Healthy Gut by Adored Beast Apothecary may work for you. You can also try making slippery elm bark syrup. Bring...
Tuna or any fish, and chicken are the two least tolerated foods by kitties and can cause vomiting. Try a different flavor such as rabbit, duck, or venison and see if she stops.
Keep a log of her behavior, litter box usage, her play, and her eating habits. She could just be reacting to the shots, but she could've picked up something at the vets from all the stress. She could also be reacting to the shots. Have you tried baby food yet?
Do you have a heating pad? You can wrap it in a towel for him to lay on and that will help soothe is aching joints. I don't think it's an emergency as long as he is eating (even if enticed with treats), drinking, and using the litter box.
I use 2 vets in my area. One is a cat-only vet with all the latest, greatest, bells & whistles equipment and everything. One is your regular run of the mill vet that doesn't have all the bells & whistles but is up on the latest procedures and things like that. When one of my girls when for her...
Plain meat baby food, chicken or turkey, is always my go-to when my kitties aren't eating their regular food. Then, I'll try mixing in some of their regular food with the baby food, not too much. She most likely is feeling the after effects of the shots. If she continues to not eat over the...
I have an almost 14 yr old male kitty who was also a wild child in his youth. Thankfully, he's reformed! Kitties are prone to arthritis as they age, just as humans are. Did the vet check for arthritis or talk about any arthritis supplements?
The enlarged kidney could be genetic and just normal for him. Gastrointestinal problems can cause all kinds of problems. I would see if you can afford the pancreas test and/or the GI panel, which will test the pancreas. The GI panel requires fasting for 10-12 hours, but is a quick blood draw. I...
Try a food that's not chicken or fish. Many kitties respond well to rabbit, venison, lamb, turkey, or duck. Sometimes duck can be problematic if the kitty is intolerant of chicken.
Ask the vet for anti-nausea meds as nausea can cause vomiting. Request they check pancreas and do a GI blood...
There are several things that can cause increased thirst and weight loss such as diabetes, thyroid issues, and gastrointestinal issues. Excessive drinking is often a sign of nausea in kitties. From these results, I don't see anything that would indicate kidney disease. You could, however, be...
