Pet's info: Cat | Mixed Breed | Female | spayed | 8 years and 9 months old | 5 lbs
12 months ago cat had huge lump on side which disappeared then left massive open wound - it cleared up beautifully but now she had another one on her chest area about the size of a £2 coin which looks about 1/2 deep and yellow inside - what is it and what should we do? She is eating and drinking and toileting normally and doesn't appear to be in pain. There is no blood or oozing.

These each sound like an abscess that healed but trapped the bacteria under neath so it opened up and drained. The yellow inside may be fat or necrotic tissue. Clean it with soap and water on a cloth until you can take her to the vet. typically they heal very well and quickly but will need antibiotics to make sure the infection is gone while it is healing

Hi, this can be a number of things. One is a cyst that has hard yellow material in it. Another is insects or maggot eggs. If your cat goes outside and it is warm where you live, an insect infestation is more likely. I would bath him and brush him out, then wash the area betadine solution, while flushing out the hole. You can get a syringe with no needle to do this. Squirt the solution into the holes and flush out any foreign material. This will also help for an abscess or cyst. Do this 3-4 times a day for 3 days. If the wound does not heal or you keep seeing the seed like things, take him to a vet. Good luck, i hope this helps!
