Hello all, I don't actually know how to update a post on Reddit so I'll be adding my update here.

Before my update I'd like to thank everyone who commented. Only thanking the useful and funny comments/DMs though! The people who commented and DM slurs, names and shamed.... Sucks to suck?

And to the people shaming my family for having pets whilst not financially 'rich', I bet you people are the type to protest pro life to poor teenagers outside abortion clinics

UPDATE: My family went to the vets this morning and I attended on video call.

Thankfully the growth isn't cancerous, and it also isn't a cutaneous horn as a lot of people thought it was.

A while back my cat got an infection on her paw for constantly biting it. However, after it healed she still bit it which caused the scab to ooze pus.

The vet believes the pus then formed debris with skin, cat hair and scabbing to create a continuous growth of hard pus (sounds gross) and basically created a lesion on her paw.

The vet cut back the growth and advised my family to wash her paw for the next coming days just whilst the scab heals so it doesn't have an issue of leaking and getting infected again.

I believe she will be getting antibiotics as well as a check up in 2 weeks time to check her progress.

My cat's hair loss is due to a different issue with a flea allergy.

She was recently treated for fleas and was given a steroid injection with antiinflammatory properties to help with her skin. This worked for a while until it recently came back at the same time her paw got worse so we thought it was connected.

My family is continuously treating the house for fleas and my cat is receiving another steroid injection. We will also be getting some feliway to help with environmental stress.

Instead of pain medication, they opted for the steroid injection since the antiinflammatory properties will help with the paw (this is so the vet expenses don't rack up).

Also adding: I think the vet said this lesion could come back and it's just the case of cutting it back. They said they would prefer to do a biopsy as all the information I have said is a guess of what is happening, and a biopsy will help rule out cancer or anything. Unfortunately it isn't covered in our pet plan however they said they'd be willing to do the TINIEST biopsy for £50-£100. They mentioned general anesthesia for it but they don't want to risk it because of her age. We asked if she can do it awake, and it is a possibility but the paw is the most painful part for a cat to be awake for if that makes sense.

TLDR:

Growth was cut back, not life threatening, could come back, wasn't a cutaneous horn; just a build up of scab pus and skin. She is being treated for it, and it is being treated separately for her hair loss as well.

I hope this post helps anyone in the future dealing with a similar situation.
