Two Cats Fighting on a Wall (Dos gatos riñendo sobre una pared)

This overdoor piece is somewhat problematic. When it entered the collection of the Prado (it was probably Cruzada Villaamil who drew up the inventory of the newly acquired works) it was considered to lack artistic interest and it was not attributed to anyone. The work was then lost in the museum's collections until Sambricio included it - with some reservations - in his catalogue of tapestry cartoons by Goya, although he never had the opportunity to see it and he did not include a reproduction of the image. Based purely on the tapestry, the author added that the composition was really quite unfortunate and bore no resemblance to the technique of Goya. It was not until 1984 that Mercedes Águeda finally found the cartoon in the museum and once again insisted on Goya's authorship. Arnaiz agrees with Vicente López and Águeda and is of the opinion that the painting is entirely in keeping with Goya's style of painting.

However, the American writer Janis Tomlinson is absolutely opposed to attributing the work to Goya, arguing that its composition is completely mediocre, that there is no consistency between this work and the rest of the series, dedicated to the seasons, and that the first mention of the work's transfer to tapestry comes considerably later than that of the other overdoor cartoons made for the dining room. She adds that it may have been the work of a secondary artist who worked for the factory during the years in which Goya did not.

Furthermore, the dimensions of the work that were provided in the inventory of 1870, when it arrived at the Prado, were wrong. Neither does it match any of the stretchers included in the invoice from the carpenter, Serrano, unless the dimensions of one of these was also incorrect. In any case, the stretcher for this work's companion piece, Birds in Flight would still need to be accounted for. According to Águeda, both works would have hung on the same wall as The Snowstorm, whilst Sancho places it on the east wall, forming a pair with Birds in Flight.
