Cat has breast cancer on one side. Has large nodule on cheek. Hairless, normal skin color, hard w.ith fluid center that drains a thin sticky clear fluid. Rapidly getting adjacent ones of various sizes. Occassionally gets scratched and bleeds but does not seem itchy. Cat is 14, female, spayed Maine Coon mix. No other health issues. Acts, drinks, eats normal. No known allergies , no fleas. I just clean it with peroxide as needed. What might it be and any treatment?

Mammary growths in cats have a high chance of being a malignant cancer. Since they are open and draining, they may also be infected It would be best to have a vet check the area to see if surgery is an option to remove them or at least medication to help clean them and clear the infection. Peroxide can actually delay healing after the first use. You are safer with mild soap and water to wipe it clean

My puppy had parvo virus. If I bring a fully vaccinated dog here, can it infect the new dog? Is there still a risk?

If they new dog is a year old and you are completely sure that that it is 100 percent vaccinated there is a very minimal risk that it will be infected. However, that being said, vaccines are never 100 percent effective so there is always a 0.09 percent chance that the new dog could get the virus. But you should be safe bringing the new dog home. I would make sure that the home environment has been cleaned as thoroughly as possible (this means with bleach to all surfaces) and make sure that the outdoor surfaces have been cleaned as well. Parvo can live in the environment for an annoyingly long time (up to 6 months) so it wouldn't hurt to apply a safe mixture of bleach product to your yard as well. This is probably going completely overboard, but you know how scary parvo can be!

My barrel racing horse is refusing to eat. She stands with her butt against the stall wall and rests her hocks. She usually stops this when I exercise her. What is going on?

If she's not eating, she's eating painful, colicky, or both. Take a heart rate if you know how to do this--normal is 20-40 beats/minute. If it's higher than this, she's painful and needs to see a veterinarian. If she is rolling, looking at her sides, or not passing manure, she needs to see a vet as these are signs of colic. If you really think she's resting her hocks, then they are sore, and she needs xrays to see what kind of arthritis is going on and what steps you need to take to make her more comfortable. Hope that helps!

I have a cat that as a kitten was very ill. We got him from 7 months old. We knew he’d had cat flu prior to him coming here. He is now nearly 5 yrs old. He picks huge fights with our other cat. He keeps urinating and scratching at doors and windows around the house. We allow him to go out via the cat flap unlimited. What is happening to him

I'm glad to see that Pippin has been neutered because this eliminates that possibility of hormone-fueled behavioral changes and aggression. Behavioral changes in cats can occur at any point in time, and could be related to anxiety or stressful situations (even rearranging furniture or introducing new people to the home can be stressful to cats). Without a lot more information and observing Pippin's behaviors, I can't precisely tell you why these changes are occurring. It may be best to consult a veterinary behaviorist in your home so that they can observe everything firsthand. You can also try using calming pheromone collars or diffusers (Feliway is one example), and discussing the use of anxiety medication with Pippin's vet. I hope that all goes well!

Hi! My cat was recently diagnosed with diabetes. He’s taking insulin and taking antibiotics for a Uti. It’s been 4 weeks and he wobles when he’s walking. He can’t jump up on the bed like he used to.He’s blood sugar is 250 it’s better than it used to. I don’t understand why he’s so wobbly.

Cats can develop what's called diabetic neuropathy, where their hindlegs become progressively weak. The best thing to do is try to get his diabetes under control as quickly as possible. Here is a link describing the conditon: http://www.diabeticcatcare.com/DCCCOK/Neuropathy.htm

Can I reapply flea treatment early? It’s been 2 weeks with no results.

A [flea](https://www.petcoach.co/article/fleas-life-cycle-anatomy-disease-transmission) infestation on your pet or in your home can be [difficult and frustrating](https://www.petcoach.co/article/why-are-fleas-so-hard-to-kill) to deal with. Yes, if after two weeks the [flea preventive you applied isn't working](https://www.petcoach.co/article/6-reasons-your-flea-prevention-isnt-working), you can reapply flea treatment early, or switch to another brand. I recommend using Advantix or a chewable prescription product from your vet, like Bravecto, Nexgard, Simparica, or Credelio. This recommendation is unrelated to Petco or PetCoach. If you are seeing fleas on Mia now, you can give her Capstar ([Nitenpyram](https://www.petcoach.co/pet-medication/nitenpyram)). It's a one time pill that starts killing adult fleas in 30 minutes and is safe to use with a topical treatment. Use a monthly preventive on all pets for at least 3 consecutive months to break the flea life cycle. Year round use is preferred. You will also have to [treat the environment](https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas). Wash all bedding in hot soapy water, and vacuum the furniture and carpet surfaces. Discard of the bag or empty the canister outdoors immediately afterwards. Use a spray, such as Indoorex or Knockout ES, in the house and to prevent reinfestation.

My senior cat has metastized cancer.17 yrs old. My vet gave her predizone1 and one half tabs a day.i wanted to know if i can just stop the meds.

Is there a reason you want to stop the prednisone? I would recommend not stopping it and if you feel it is better to stop the prednisone then I would recommend weaning off of the prednisone. I would discuss how to wean the prednisone with your veterinarian. Thank you for using Boop by Petco.
